It's been a great compliment to poshmark and ebay for buying used items online. I've had no problems with the credit card transactions. The only issues I had the low end of bidding amounts seems to be capped so I can't bid more than the 20% of the asking amount. Also I can't search from most expensive to least expensive. I can only sort by least to most expensive. Overall, everyone seems pretty trust worthy. I like the app, but there is definitely room for improvement.
