I collected cards for 3 years when I was younger. I have upper deck '90-'91 to '92-'93 full sets plus a bunch of doubles. I know these collections are very popular as most kids started collecting in the early 90's. I've recently grabbed all my cards from my parents house and and thinking about getting back into it. After looking around my area (Guelph, ON) I noticed the only card shop in town has closed down. So other than card shops, where's the best place to buy cards? Is it really worth buying pack by pack from convenience/department stores? Where's the best place to buy boxes of packs?
