When I went I bought enough for 3 racks ... 1 large & 2 small

the price for the small tubs was $4.98 each, large tubs were 11.47 each.

31 - 2x2x8 = 67.89
8 small tub = 39.84
4 large tub = 45.88
1 box staples = 3.66
2 - 2x4x8 = 5.94
1 box screws = 4.11
5 - 1x2x8 = 9.45
--------------------
total = 176.77

took about 3 hrs a piece to build em (alone).

In the first picture you can see the top is divided, one side is for lab block, the other for food (thanks "Wild Bill" for the idea), the hardware cloth is 1/2" x 1/2".
