1. or you can buy one that's on sale... or has rebate.... and then sell it at below full price.
2. or you can hunting around at garage sales or flea market... and then sell it higher
3. ebay allows only 1 free photo and then they charge you for additional photos so upload your photos to your own site and then link it.
4. it's good idea to add $2-3 more to S/H fee
IMO - you'd probably profit more on antiques than electronic accessories and small electronics. Check around certain categories in ebay to get some idea what to sell. meanwhile - it doesn't hurt to sell comp-related stuff as well.
