If you search for "bed bands" on Amazon there are (at the moment) 333 results returned with the trademarked (?) "Bed Band" brand at the top of the list.
In general I find this a problem with Amazon searches -- even if I provide a specific model number for something they return a shitload of "similar" and not-so-similar stuff with nothing to indicate that one of them is the exact match. Sometimes there is no exact match and they just return a bunch of stuff that maybe I'll buy instead anyhow.
This is also the case with NewEgg; I was bitten by that after searching for an exact model number, getting a single product returned, and buying it without realizing that they just matched me with something similar but different. In that case it was too different for my application. The joke was on me.
