Chewy is awesome. Great prices, product selection, and customer service. It's really nice and convenient to have a huge, heavy bag of dog food shipped right to my door. Same price if not better than what I would get from my local store.
You can win, but watch what you're doing. Some people just spend and spend just to win. Then they get mad when they've spent more than they think they should have. I have won, and it is really fun. Just don't go crazy chasing the win.
