Do you also track unsold items? That was the question. Say someone offers the $7 McCarran in your example, for $200 and gets no bids, does that get included in the database, or just sold items.

As for the cost of the site or your expenses, that's fine. If I say a car gets 30 MPG and gas costs $1.56 a gallon, expected fuel costs per year are $700. It's just numbers... everyone can decide for themself whether $5 a month is right for them to have someone track the silver strike market.

It's not for me because I have a bunch of common strikes and not that many. It would be for someone who has a "serious" collection.
