What do you find the most frustrating about collecting

[HIPPEEDUDE]

Having to sell some things because you are running out of room.

On shipping costs,its always going to be a killer when it comes to a deal. Many times i have paid more for shipping than what the actual item costs but,the one consolation is when i have done that it still works out cheaper than what the item would normally cost by itself. As an example,a new sealed Fallout 3 GOTY collectors guide is averaging $100+ i got one sent to me including postage for $90,postage was $50 & the book was $40. So to me thats a win & i dont mind the postage being higher than the cost of the item.
