I don't actually own anything from Tory Burch so have no experience with what their quality is like! I did do a search here last month and I don't think I could actually find much mention of the Tory Burch bucket bag though, think it just hasn't really been talked about much at all...
I do like Coach (as evidenced by the several Coach bags I own!). However I don't live in the US and I'm not sure how the warranty works overseas, as have never needed to use it. (Actually... I wonder if should test it out - one of the small wallets I own and bought last June - according to the receipt exactly a year ago! - is starting to come apart at the button...)
Also I love blue, and the blue colour for this bag seems to look amazing on their website!
Anyway, will be visiting the US next week so am looking forward to seeing what the bag looks like in real life! They have it here but it's £445 which works out to $690...! A bit annoyed that I'll have just missed the Lord and Taylor 25% off sale though, but think at least Macy's has the 10% off visitor discount...
