how can we work out how much we pay in fees on top of the auction price?
This information can be found in the FAQ section of the site:
1. What fees does bidJDM charge?
There are no fees to bid on auctions but you must pay your bid price upfront before bidding. You will have to pay to bid but if you do not win the auction your account with bidJDM will be credited for the amount you bid so you can bid on other auctions or raise your bid on that particular auction you were out bid on. If you win an auction there are 2 fees you have to pay plus the shipping of your won auction to your country. The two fees are;
1. The final ending bid fee. This is a percentage fee taken from the final auction price. The percentage will depend on the category the auction item is listed under and can be found on each auction page when you click "Bid Now".
2. The size handling fee. This fee is based on the size or weight (whichever is larger) of the item and the location the seller is shipping the item from. This chart can be found on each auction page when you click the "Handling Fee" button and you will be able to very accurately determine how large the item is from the pictures and figure out what this fee will be before bidding.
