Check your product library before buying.

I purchased the Carter 9 HD Character Bundle, but it does not show up as "purchased" on the page. I remembered that I already bought this and it's in my product library, but if I didn't know better, I could have easily bought it twice. From now on I'm going to search my product library for any item I pintend to buy before paying, and I suggest you do the same.

As a possible tip, hit refresh first -- sometimes things that initially show up as not purchased will change to purchased when I F5 the page. Might save you needing to go search if you have it. :)
Instead of searching product library, you can just check on the page. If it has a download icon instead of wishlist icon, you already own that product. In my case, refreshing page once clears that glitch and shows the product as purchased.
With all the drifting of PAs and products over the year between DAZ, Renderosity, RDNA, Content Paradise, Rendorotica/CGBytes, Renderhub, etc., it's always advisable to check your back records when purchasing anything that's not obviously a brand new release. It's a huge pain, and the fact that some of the vendors have opted to change their names only complicates the issue, but otherwise you're going to end up double-buying.
