You sold all three collars as a lot for 99p, plus £1.99 postage, total £2.98.
EBay's 10% selling fee will have been 29.8p, and Paypal's fee about 39p, total about 69p.
By my reckoning, you're only left with 20p of the 99p you sold them for!
The moral is to start listings at the lowest price you would be willing to accept. This means working out in advance what will be left after fees. Remember that these are charged on the full selling price, including postage.
