Yeah, that sounds like it'll work just fine. Just as long as it has drain holes, I don't see any reason why it wouldn't work. If you want a good site to buy plain plastic containers for reasonable prices,
check out this place. I've had some trouble finding plain plastic containers in stores around her as well...like you said, all they sell are expensive 'fancy' ones (which I could care less about, being the minimalist I am LOL
).
