Well I pay from 5 to 20 cents per listing for items in my Store. While my FVF is slightly lower, the 50 Free Auctions cost less in money.
But with over 5000 listings on my various IDs, the extra labour for constant relisting would add up. (At 17 cents a minute if you use Ontario minimum wage.)
If you have over 54 unique items listed, look into the cost of owning a Store.
