One tip- once you see something you like, you can double check if Amazon has it. 6pm also sells through Amazon. The benefit of this is that if you have a prime membership then you can buy through Amazon and get free returns if necessary (6pm only offers free shipping on deliveries. Buyer pays return shipping costs).
I bought 2 pieces of china recently in my wedding pattern (an extra platter plate & serving bowl) from 6pm at 1/2 price that Bloomies was selling them for. They're run by Zappos, super legit, great deals if they have what you're browsing for!
Yes 6pm.com is legit...they have Great prices on lots of things!!! I got some Levis for my kiddos for like 7.00 a pair !!! Plus free Shipping!!! Yeah buddy!!!
