yeah certainly had some good mojo from there recently. definitley getting my money's worth with the Magic auto a few weeks ago now these.
The thing is every time i have gone in there or my MRS there has only been a few packs left in the boxes so they always open up a new box for me and let me choose the packs. With studio i always grab them from the middle column. Seems to be a hot spot for them. Classics i just grab randomly, no system there. I also normally leave it a couple weeks between buys so they can sell out of the boxes i buy from and get fresh stock in.
Actually atm they have a good sale on with 10-20% off some of the packs. Still over priced but they scratch my itch
