Unless you have a local wholesaler (I have NO money) I use http://www.drsfostersmith.com, because they eat the price on shipping, even the largest, heaviest cages come for $10. shipping, whereas the others charge $60. shipping, same product. All items, even in separate boxes, come for the same chg. so shop wisely. Get all at once. I find the mail catalog to be cheaper than the on-line. You use the phone to order, they are open 24/7 and ALWAYS someone friendy and helpful, w/ all the time in the world for you, will answer, even at 4am... Love them...
