I appreciate all your opinions. I'll give mine. I hate that UD stopped putting the jumbo YGs in a cello/plastic, many come damaged out of blasters. I'm not a big fan of the copper/gold OPC Glossy being so similar, if you don't have both you're always in a doubt about what you have. I developped an appreciation for the 1994-95 Tribute cards and the odds are slightly better at some pulls in the megas, so at full SRP my first choice is the megas when buying from Walmart, but usually I pass.. During the black friday/boxing day sales, I pick the format they have in sale and I stock a bit for the rainy days.
In the past, I've been buying older retail 24 packs boxes at really good price. UD1 14-15, UD2 15-16 and UD1 17-18 at around 40CAD were really fun. But those days are long gone!
With all the hobby wax so expensive now, I'm thinking of going for 1 UD2 20-21 mega at release for my birthday. My next purchase after this will be SP retail 20-21, probably a couple of boxes. I did well with the single box of each previous year I opened and I really like the RCs /1199.
