factory showroom

Here's a question. Is it wrong of me to buy up Topps factory sets just to open them up and go through them? Now I've missed a lot of years here. I have various Topps cards from 1952 to now. I have obtained them all within the past 5 months or so. I collected when I was younger and I had my vast collection of 1987-1991 Topps and boatloads of 1987-1990 Donruss, some 1991 Upper Deck, plenty of Score, etc. You get the picture. While I enjoy collecting the sets, opening packs, hunting for single cards I need, it all gets expensive. Quickly. Especially when Topps collation is tricky. I find myself buying packs just to get a final couple of cards I need for my third full set. Its that compulsion thing. Gnaws at me, heh. So I finished 2010, I'm now 1 card short of 1987 (which is coming), and I picked up cheap on the 'Bay 1988 and 1989. I bought 1997 (apparently a tough year to find) in my local card shop, just sitting on a table, begging to be bought. Also coming from eBay are about 7 more various years. It is essentially just to play 'catch-up' on all those years I missed in the years I didn't collect. Yes they get opened and yes, they get put into numerical order. I enjoy it (for some reason), and its does do good catching me up on what I missed out on. I do have a rule though; I only grab them if they are sealed and if I can get them for under $20-25 including shipping. Which is tough because they are heavy, and usually run anywhere from $7.50 to $11.00 for shipping. Regardless, I think this is the best way for me to get the full set and see what I missed.
