Okay, so on my two retired collector pack (July/June 2011) I was offered a custom wear (Ethereal Filmy Dress).

Now my collector packs are worth about the same as a 500+100 credit csc cards would be.

However, I wasn't sure how well custom wears sell?

This isn't really something I'd use, I'd want to resell it, but would it be easier than trying to sell the packs?

I think the donation presents would be easier to sell, CWs in the cash shop (as that one is) are very hard to sell over 500 CSC, I think.

CWs vary significantly in pricing. Some are worth a ridiculous amount (limited batches) and others sell for next to nothing (I've seen some under the value of 250 CSC.) Donation packages only ever really increase in value, depending on how many there are in the shop at the time.
