FedEx dropped my 4 off at the local shop yesterday and this morning I paid the remaining balance and picked them up.

They're individually bagged in appropriate size zip lock bags with a sticker on the side containing the part number and description. I wonder if part of the delay/shortage was the manufacturer waiting for fancy retail packaging. I got a few 32-round 15-22 ProMags and noticed that they too were in zip locks with basic stickers on them rather than full retail packaging. Maybe the packaging suppliers are overwhelmed as well or maybe on-line stores are able to get products like these with minimal packaging
In other news KyGunCo has shown since last Monday (3/11, the day before GOG had the mags come in stock) that the status on my 2 overpriced ($60+S&H each) magazines ordered 2/23 is "Shipped USPS Priority Mail Scheduled to arrive in 2-3 days". Nothing in my mailbox as of today and no tracking number visible on their web site or emailed to me. They're getting a call Monday and I'll be requesting a tracking number and if they haven't really shipped yet I'll be requesting a refund.
