I purchased stuffbak a few months ago, and it seems reasonably straightforward. One thing I like is the variety of stuffbak labels and tags which can be applied to everything from cellphones to keychains. ^

Seems like a small price to pay, as many lost items go unclaimed because the finder (e.g. airport/airline employee) is unable to contact the owner. Call me crazy, but I think most people want to do the right thing, and "reward" provides that last little push (though you may wish to consider offering a cash reward as the std stuffbak award is payment-in-kind).
