This is a good place to go if you know exactly what you want, although many of the prices are higher than the local pet shops.
If you are after valid information, especially about birds, don't even think about asking. The people there have little or no knowledge about care, they are just cashiers. I would much rather support my local business's for many reasons, but most of all because they know what they are talking about. This has saved the lives of many pets!
