I just got offered a job at Bed Bath and Beyond as a Sales Associate, need advice....?

I would like to know from people who have worked or work at Bed Bath and Beyond how their experience was. I interviewed for a sales associate position yesterday and was immediately offered the job starting out in "housewares". The lady who interviewed me was a bit vague about what my job duties would be. She told me that there are shifts that start at 4am or 7am and I cannot make these shifts because they are too early. She also told me that I would have to climb all the way to the top of the shelves every night and remove the stock to the bottom shelves, which is dangerous given the height. She also told me it was very "hands-on" and I would be stocking but she didn't tell me how much I would be stocking. Would I need to do shopping cart duty (as in shopping cart retrieval from the parking lot?) or do the stock guys do that? Is it a good company to work for? I have a week to make a decision. BTW the store is the one in Aventura, Miami, FL. Would be nice to hear from anyone who actually works there! Thanks.
