I shop around for deals so I don't always use the same exact site to purchase products. I buy bulk items each time I make a purchase so whichever place have the better deal and free shipping is even better is where I make my purchase. I basically do a lot of google search for products and read page after page until I find the deal.
While they do have a physical location here, they also ship nationwide (free if you order $50+ and how easy is that!) and have great products and fast shipping. The people are also wonderful, they truly care about birds and always do their best to offer the best.
