Reebonz has lovely packaging yet comparably poor customer service and slow/ unpredictable shipping (bought vintage Chanel). Most of their stuff is now final sale, so... moving on...
Stylebop has AMAZING customer service. Really exceptional (bought large Ferragamo Sophia - received small and they went above and beyond to resolve).
Have used Farfetch (Givenchy Pandora), Forzieri ( Wang Rockie), and Outnet (Rocco), and Yoogis (vintage LV epi noe sling; Bal Day). All as expected- uneventful, as they should be.
Fashionphile (Bal velo) - like the buyback-for-70% option.
Always exceptional experience and service - in store and online- w/ Barney's,
Nordstrom, Neimans, Saks, and Bloomingdales. I value the experience and the service and like to buy in store. Having said that, I live in a HIGH sales tax state, so the online curators ( Farfetch, style bop, Forzieri) can be great savings just from no tax, let alone good deals.
Great deals at Rack and TJMaxx Runway. They're all about the deal... Experience, not so much. I'm OK w/ that.
Tradesy- great response when I thought I bought a fake... Learned here that it was in fact authentic and told them. They responded immediately to the concern and the resolution. They were great.
EBay- not much to say.. It's eBay. I mostly avoid. Bonanza- bought and sold a few times to/from lovely sellers, but haven't looked there in years. Have become friends with a couple of sellers well outside Bonz- kind of cool.
Amazon- used to buy bags there a lot ( in my frenzied RM days, long past). I no longer shop there for bags, but I buy All The Other Things ( subscribe and save!)
Wow. Scary to see all that buying experience...
