Stacking discounts

  The store is calculating it correctly. Percentage discounts are applied one by one, not all at once - so you are getting 30% off of the remaining price after the first 50% discount has been taken. (Hence, as the 50% halved the price, the 30% then equates to 15% of the initial price, which is why you have 50+15=65% off total).

  If it was done the way you were adding them, then in theory discounts could stack to over 100% and Daz would end up owing you money.

  As stated above, stacked percentages go one after the other rather than being added together. If you had $10 and I said I was taking half (50%) and then I took half again, you'd end up with $2.50, not $0.00

  Thanks, that explains the 65% in my basket. I still believe it's a misleading marketing trick and the copy is not clear. I also don't see how, in my example, they would end up owing me money. The total discount would be 80% of the base price, I would need to pay 20% of the base item value.

  It is too early for math but imagine if you had three stacking discounts: 50%, 25%, and 25%.  As math normally works, if you buy something for $100, first discount cuts it down to $50 (50%), second discount takes it to $37.5, and final discount takes it to $28.13.  Using your logic, product is free (discounts total 100%)  which is not how stores work.  It is very easy to get three stacking discounts with a new product discount, a premier discount, and a promotional discount.

  I understand the math, I just think the copy is misleading "50% off “Shining” Artist Stores Get an extra 30% off*, especially for a non native English speaker. In any case, now I know how it's calculated, thank you all for your help.

  Oh, trust me, it's misleading for many native English speakers too.

  Those of us who aren't American eventually learn that Daz couldn't do it any other way. There are times when you'll end up stacking 6 or 7 discounts in ways that Daz probably didn't predict when creating the sales. If discounts were additive rather than cumulative, everything would end up free at some point. Or maybe even there would be situations where Daz would owe many of us thousands of dollars. I wouldn't put an error like that past them!

  Today, there are many stacking discounts available. You can probably do even better than 65% off. Look at all the sales - there are some discounts that interact with one another.

   True  A decent sale. 4 items from my wishlist plus the cheapest Shining (plus 1 unused token, plus my $6 coupon - first I seem to have used in ages! for a little bit more than 80% off. Might have made that almost 90%, but would have cost more... for things I wouldn't use).

  Also thought the deer product (I think released yesterday/today?) is one of the loveliest products released in a while.

  If it was meant to add it would say "an additional 30 percentage points" (or more likely it would just say get  X% off, or Y% off with a new release). As has been said, this is correct both in maths and English - though percentages can confuse many people.

  There is no business on Earth where percentages are added together. They are always done sequentially. People who are new to business practices might be fooled by this. Have you gone grocery shopping with coupons? "Plus an additional 30%" is how sales are written for as long as I've been alive (50+ years).  And it is how sales will continue to be written long after I'm dead.

  Technically you learned this in like 3rd or 4th grade when you learned order of operations is multiplication before addition. Percentages are multiplication operations. You are trying to add before multiplying. Of course, a good education system would give real world examples such as stacking discounts.

  I respectfully disagree as I have done previously. And that's okay - we can have differing opionions. But to mirror the black and white reasoning, you're also absolutely wrong I understand you probably have responsibilities to serve, but please be careful with language and those who don't speak English as a mothet tongue. It looks like you're trying to confuse people, and that may be counter-productive with that moderator label next to your name.

  For anyone who isn't a native speaker of English, extra and additional are used interchangeably in maths as they are in language. The context in which they're used can certainly change meaning - indeed, there are plenty of examples of sales text that uses extra off as addititive (it's certainly the most common use in the United Kingdom). In Daz-land, however, the important context is that today, as during all yesterdays that I'm aware of, Daz use extra to mean cumulative. No biggy. Most of us learn it, move on and keep our thinking flexible in other settings.

  Close to fifty years ago I was at the checkout register for more than 30 minutes because of multiple discpounts.

  There was a white goods sale, 50% off. There was a household items department sale, 30% off on $100 or more. And there was a store-wide promotion, 30% off if you opened a store account. IIRC, the actual amout was around $109, but I'm going to round it to $100 to make the math easier.

  The first couple of go-rounds with a pair of junior clerks went like this - 50% of $100 is $50; 30% of $100 is $30; and 30% of $100 is $30. So 30 + 30 + 50 is 110 - and that can't be right; he gets all this (gestures to my stack of towels) and a store account, and we owe him $10??

  Finally a senior clerk got flagged down and said it works this way. 50% of $100 is $50; so $100 minus $50 leaves $50. 30% of $50 is $15; so $50 minus $15 is $35. Finally, 30% of $35 is $10.50; so $35 minus $10.50 is $24.50 and that is what he owes.

  And that's how stacking discounts work.

  I did acknowledge that this is something that a lot of people find confusing - even news outlets have had to issue corrections after getting muddled - but the process and terms used are correct (well, usually - there have been occasions when an incorrect decription was used, I think, but not recently).

  And all this confusion is why I usually avoid all those "sales."

  And I recently quite the Premium membership because I couldn't find anything all that appealing.

  More discounts, all businesses are doing it, this is how it works, you learn this in the 3rd grade wonders today: Product page tells me I have to pay 3.99 (80% off). I go to basket, magically turns to 5.10 (74% off).
