target has the 32 or 34's i forget which. because when i bought my rack i couldn't find the tubs and ended up ordering these from walmart and they were cheaper.

i run em with out the lids and no escapees. to much of a hassle to do stuff. had to pull the lid off every-time after you slid the tub our or back in.
