A friend of mine told me about a collectible swap meet called "Frank and Son Collectible Show" in the City of Industry in Southern California. There were many booths that had sealed booster boxes for sale and one huge Wizards of the Coast Distributor's Booth when you first walked in. I bought most of my cards there, but sometimes you could haggle with the little dealers too. I would go there with my kids at least twice a month for a couple of years until I had to have major hip surgery. They opened many booster boxes, mainly the unlimited ones but some 1st Edition ones too.
The ones I kept for all these years are mostly 1st Edition. By the time I healed from the surgery, it seemed that my family had lost interest in Pokemon cards and we stopped going. I've had all of the sealed booster boxes stored safely in my home since they we first released over 20 years ago.
