I for one appreciate them keeping these items posted on their website. It helps find part numbers and descriptions for doing advanced searches on eBay or the internet in general.
Perfect example, my posting in the classifieds looking for Barracuda Studios decals. When I did a Google search for "1/32 Aleutian Tiger Decals" Barracuda Studios website came up with the part number and exact description of what they called their product.
Although out of production and out of stock, it is still providing very valuable information to assist me on the hunt.
I find it helpful that retailers keep this stuff around forever.
It helps you determine if a kit is basically out of production among other things.
