I've used all 3 as well. No issues for me. The good thing about ebags is that they have their own lines of luggage which tend to be cheaper than the big brands but comparable quality. I guess they cut out the middle man. Plenty of 20-30% off sales as well and free shipping offers. Plus they have nice Ultimate Rewards mall bonus points. The disadvantage of Amazon is that they don't particiapte in any of the mileage program shopping malls.
