Wishlist/Checkout Annoyances & Warning!

So I was reading about a big sale right now on some older items and thought I'd give my wishlist a browse to see what I might pick up.  I added about 9 items, and, because I've learned to check the material presets for 3Delight as I don't use Iray, I checked each one to make sure it would work for me.  Here are the problems I found:

1) Two items were add-ons and, when I went to add them to my cart, they both said I needed to purchase the original.  I almost put the original in the cart, but thought I'd check first.  When I opened the add-on products up in their own tab, they both said I already own the original (which I do).  I refreshed the cart and the wishlist and that fixed itself.

2) I added a G3F figure that had been in my wishlist for some time to my cart.  I then, from the cart, opened the product up in a seperate tab and it said I already owned the product!  I checked and it was already in my Product Library!  I refreshed the wishlist and cart again and it disappeared.  Why didn't this get fixed when I refreshed them the first time?

Seriously... this is just BAD.  How many people have bought an item they already own because the database on Daz's server isn't working right?  I just about spent $25 for items I already owned.  How many are in my library paid for twice and I'll never know?  Granted, some are from packages where the savings out-weighed buying the items I still needed seperately, but that's pretty rare.

This having to double and triple check stuff before you hit the purchase button is really eroding my confidence in Daz, and I highly recommend everyone to make sure they double check their cart before purchasing!!
