Hill33 is right. It may come across as addiction but I've been doing this so long its just what I do. Unlike most addictions it doesn't alienate family, friends and I can afford my bills so keep it up I say!
Welcome to the boards. I'm sure you can offload some of your stuff and get some new stuff to replace it. Its a different world these days and like Geelongfan said boxes are now a form of card gambling. Take the plunge or pick up singles. Depends on what you want really.
Most of all, have fun collecting.
