What kind of things are you looking for? Different companies specialize in different things (for example some places have really good cages, but a poor toy selection or great toys but no cages).
I would definitely suggest checking out my safe bird store then! They run great deals, and have free shipping when you purchase a certain amount. Plus the toys are awesome!
I do know a few of the owners of these stores (since they do belong to some forums and chat about their birds). Some of the stores may have coupon codes, and may have special deals going on throughout the week or even on weekends. Check the stores out and see what you can find!
The stores located in Canada do ship to the USA, too!
