Heads up, you've gone over the 30 items criteria so eBay will be reporting your sales to HMRC, who may send you a 'nudge' letter to confirm that you're listing your own personal possessions and not trading as a business (i.e. buying from bootfairs/charity shops). Things that get you flagged up will be clothes/shoes in lots different sizes.
If you are buying to re-sell you'd be way better off trading on a business account, you can then claim expenses.
