I have purchased a few items through them and consigned one. Every time I have bought online, the items have never come in the condition listed on the site, resulting in me asking myself: “okay, can I live with this?” Most often, I just don’t go through the hassle of returning. Now, if I ever see something I like online, it has to be in the SoHo store where I can look at it. Still, I have found pristine items with tags at the store are often not pristine when I arrive to look at the items, though they may still have the tags. Excellent items, which they deem to have no wear, are often not the case either, just by zooming in on each of the photographs or using the store method. Be very, very careful of this when purchasing online.
If you want a bargain, end of season sales with the designers and the department stores are often your best bet. You have to have the patience of going through the racks virtually or physically. They often get the price to cheaper than this app during the sales, sometimes even when TRR has received that same item themself.
