Currently all males are $70 and females are $50, but prices may change at any time without notice.
Canaries are shipped in a box specially equiped for live birds. They are completely safe and even contain places for water and food which are always used when I ship birds. There is a $15 deposit on the shipping box because I'm sure all of you wouldn't want to have to buy these expensive boxes every time you order a bird. Normal return shipping rates for the boxes through UPS Ground are around $3-$4.
USPS is fairly cheap and safe. The shipping type used is overnight air. I haven't had any problems with it, nor has anyone I have talked with. The average price for USPS is around $35, varying on where you are located. Shipping may take more than one night if you are not located close to a major airport which USPS has access to.
Delta Airlines Animal Carrier Service. This is fairly expensive averaging around $120, however it is just like sending a child on a plane. The box is carried on board and kept in a temperature controlled and pressurized environment as opposed to just a pressurized environment with USPS services.
