I don.t know if any other HL is doing this, and I can't figure out why they do it here, but they stick new kits behind old kits. I've started looking behind the older kits, and last week I found a 65 Riviera behind a Foose El Dorado, and today I found the 60 Chevy pickup behind a 94 Ford pickup. I already had these, but a few weeks before that, I found the 59 Imperial I was wanting behind another kit. They've had the 68 Chevelle for a few months now, and already sold out of the new Mustang.
Seems to me that they would want people to know when they get new kits in, but I'm OK with it now that I know the trick, I'll be getting the new stuff before anybody else knows they are there.
