Have you felt the front? Is it "cloth-like" texture? Because if it is, it will get ruined by all the stickers. I'd have to preorder before all the stickers go on it.
Member on BD forum ordered from amazon and got the slipcover
Not getting a slipcover would apply to all retailers been hit and miss as depends on the amount of slips fox provided with the release as later copies would not be 100% come with a slipcover after release date from any retailer
I ordered lots of releases on amazon usa with list saying No enhanced packaging but got a slipcover with lot of releases
It's few weeks after release date it's less chance you get one
Amazon UK is more risky for not getting slipcovers than Amazon USA
