There is a new bamboo at Home Depot that is click lock. The manufacturer in its infinite wisdom (not) do not put run number dates on the boxes. Instead they use colored dots
Recently the HD installers were out on a job, when I get the dreaded call. The bamboo was all different shades. The sales person pulled all boxes with blue dots. But when they were opened up, the planks had different dates stamped on the back.
There was 1/23/08, 1/27/08, 4/11/08, 4/14/08 (apprx dates) The January lots were lighter than the April lots. All I had left in the store were some March lots. I took them out and they worked, thankfully.
Make sure that you see what you are getting. If you are okay with different colours, at least see what you will be dealing with. It wasn't hideous, by the way, but it wasn't great either.
Otherwise I would tell you to have them special order the product using a special order sku, because I think it's the same price. BUT, and it's a big but, this vendor is so lousy, that you will be lucky to get your products in 4 weeks.
The only other thing I've found is that the bamboo samples in our showroom scratch much easier than other floorings.
I've never sold the cork, which apparently looks better the more abuse it gets.
