I've been buying and selling on Posh for about 2 years. Overall, I've had great experiences and will continue to use them. The only thing I really take issue with is the flat rate shipping. There should be a couple of options for shipping. We're paying $6.79 for express 1-3 day shipping but sellers have up to 8 days to ship before you can cancel? So you're paying for express shipping but it could take up to 2 weeks ( or longer)?!?! That's a bit ridiculous. I think if the seller doesn't ship within 1-3 days, the shipping should be refunded to the buyer.
