This is all changing. It's not the same. You used to have a bunch of grey market PC parts distributors all over the east bay (uProcessor, add on Cards, RAM, HDD, etc) that used to sell to beige box PC makers (and individuals) but they went the way of the dodo too (ASI is legit distributor now). Also, remember WeirdStuff? Gone too.
It's a mature industry and the biz has gone largely to Amazon and NewEgg with some at BestBuy (regular people) and to large distributors like Ingram for larger players that can't buy direct from MFG or huge players who build their own.
SARS-CoV2 might have hastened their demise, but it was coming none the less.
PS. The sandwiches + a bag of chips/crisps & drink were not bad at all. Maybe it's nostalgia.
