I did it, it took me about 4.5 hours for the 300 because I am not able to move as fast as some of you can. I first did the one that said it was about 140 and that took me a little over 2.5 hours as I had no idea where anything was in the store and my getting up and down is not so quick. If it is the pet store one, no one paid any attention to me, they said hi and asked if I needed anything but when I said I was ok they just went on. I got an email after the second one that asked why so many item were unavailable. Well they want the exact name, size and code, they just didn't have it at the store. They had one for 1000 items last week, I applied and never got it for a week so I guess they will have to see someone else either not adhere to the guidelines re the weight, size, name and code or they will see that I was right. Good luck with them
