I have been collecting simpsons things for about 3-4 years now and here are some tips on not wasting money and having fun finding and displaying things. Forget that "Guide To Collecting Simpsons" because it will make you spend more money than you need to.
5. Don't buy everything from one website or store, finding things are half the fun! 4. Have a friend who collects to trade with you 3. Have a shelf or two, a bureau, desk, or stand to display your finds creatively 2. Shop around for the best prices and don't buy it all in one lump sum 1. Don't get overwhelmed that you have to collect everything, having every CD or book is just as fulfilling as having everything. Just make sure not to but one of a collection(like action figures or comics) because if you do, you will have an incomplete set
Thanks for reading, hope I helped! -Ben
