I've done business with Austin Bazaar twice and have been favorably impressed. They have both the online store and a new brick and mortar store under the same name in north Austin on Howard Lane. I first ordered a Kala KA-SEM from them online, which arrived with a small gouge in the top. Called them and they offered to take it back or refund with no questions. As I only live 90 miles away, I returned it while up visiting friends in Austin yesterday. The guys there couldn't be any nicer. I ended up putting in some extra money and leaving with a beautiful Kala Limited Edition Solid Golden Acacia Concert uke that I am very happy with.
The pros: friendly & helpful staff, large selection of ukes, and very low prices. Kala KA-SEM with gig bag, tuner and polishing cloth was $95 out the door. The Kala KA-GACG with same stuff was only $261 out the door.
The cons: No real uke expert was available to help on a Saturday. Both guys were guitar guys, very nice, and knew a bit, but not enough to expertly guide me with a uke selection. As they sell over 200 ukes a day (vast majority on line however), you'd think they'd have an expert on the floor on all shifts.
Bottom line: I'd recommend Austin Bazaar to others, particularly if you already know what you want. I'll definitely do more business with them.
