Cheapest usps approved shipping boxes, multi sized

[vetgirl00us]

nay recommended websites for usps approved shipping boxes? I need a box or two for one to 4 birds. I know one box you can fit up 4 birds and up to 20 lbs in it but need economy pricing.

This is where I got mine, their single nests (1-2 bantams) are very cheap

They also sell the economy nests (1-4 birds) but they are not as cheap.

If you need to ship 4 birds you could always use 2 singles and tape them together, that would be cheaper than (and the same size as) the economy.
