I ordered last week , $20 PSN card + Nellie’s Bulk Laundry Soda (it was on sale for $80 at that time) and I added $1 filler to get over $100,it worked for me, and I got the voucher within 10 mins,I didn't try again because I'm not a fan of digital games,I still prefer physical discs.
So I'm just suggesting if you try to mix between physical items and electronic PSN cards,it might work for you guys.
