I've been a GB member for a couple of years and currently have the 3 items at a time plan. When I first signed up, I would usually get items in 3 to 5 days from the time I notified them of my return. I started using the App and now I scan the Barcode prior to mailing, however, it takes a minimum of 5 days, and some as long as 10 before I get my next box. It's very frustrating. Especially when I end up not liking something or it doesn't fit. I put it right back in the bag. I always have a minimum of 25 items in my closet, but usually more. For this reason I've been considering canceling my subscription.
The quality of most items is pretty good. I have received some things that were ratty though. You can really tell the items that have been around the block.
Customer service has been ok. Not horrible, but they're definitely not shooting for the 10.
Anytime there is some promotional thing like get money off if you refer or get so many points if you download and use the app, I have had to contact them. For the referrals I have always had to have the person I referred send in an email. It's a pain and the referral program is obviously flawed.
I do like having a variety of clothes and this has allowed me to go out of my comfort zone to experiment with things I would never had bought.
