Hi buddy,Welcome to SR!SR's fees on seller's charges are as follows:10% on the first $508.5% on amounts of $50 - $1506% on amounts of $150 - $3003% on amounts of $300 - $500The commission is banded so for an item costing $110 (or the BTC equivalent) the commission would be $10.10 ($5 of the first $50 + $5.10 of the remaining $60).This can be a bit involved but SR does give you an option to list a price before seller fees are deducted, so you can just enter the price including your mark up and let the website do the rest.Please ask if you need anything else.V.
