Many of these contemporary vases are very pretty. Many have some deficiencies in the details, but are still okay. The thing that gives people a bad taste for these vases, I believe, is not the vases themselves, but the marketing strategies used to sell them. The listing given above didn't make any false claims about the vase, so can't really be faulted for that. It is apparent that the price of the vase plus shipping cost is $30 US. So the seller must consider $20 ($10 for shipping) a good price for the vase.
Glad that a little information might have saved you and Chris some money.
