Yeah, we run a feature store ourselves don, but we have spent some time testing and fine tunning our shipping cost to finally arrive at the figure of $6.99 per item.
That figure allows us to not just include within it the cost of packaging and postage itself, but also the cost of listing, final value fee and any PayPal fees incurred on payment transfers.
That pricing model has moved around a bit as we tested the limits, but now we can cover all those fees and still average over 4.6 for our shipping fee DSR. We also make on average around $1.00 to $2.50 on top of covering all those costs, which then goes to offset the cost of the ebay shop.
So we are effectively running our ebay format cost neutral, and maintaining an acceptable DSR ratting across the board, with our shipping fee rating being the lowest. That said, our 30 day DSR ratings average shows that the shipping cost average is getting stronger, so we are confident that we can get that average over 4.7.
Big thing with shipping price feedback, if you ship quickly you can have a seriously positive spin off on your price average, within reason of course.
