Grids, cubes & connectors on the web

What do they call the cubes and what section are they under? I can't seem to find them.

I see cubes (broken link removed) but they're $35 for a 3x3! Target often has them on sale for $9.99... I'd rather wait for the sale.

That's pretty cool. I'm thinking if I could find the supplies for a cheap price, I could sell the cages on eBay or something. But I haven't found it for cheaper than $35 for cubes and coro so far.

To find the cubes go "Complete list of products" then to "Cube units and accessories". The cubes kits are pricey but the connectors are cheap at 18 cents each. I think its a good option if you can't find connectors any place else. Also a place to find grid shelving for cage tops.

Thank you for the link lots of help. I need to order some connectors they never give you enough. Well they do for what the cubes are supposed to be used for.
