I like the marketplace but the quality of the CC on it really varies -- for instance, I thought the sets from BrazenLotus, Hydra, and Mechtasims look subpar or not Maxis Match enough compared to some other sets. It is also very disappointing to see the inconsistencies in giving the items proper descriptions -- surely this should have been made a requirement. Overall: if you're going to ask money for something that is essentially already available for free online, then at least do it properly.
There should also ideally be a way to disable/hide items you bought but didn't like, or otherwise a possibility to get a refund on them -- particularly relevant in light of the quality issues.
