Make sure you stress you're not responsible for items going missing in the post. You wouldn't believe how many items I sent, that didn't require a signature (at the buyers request, cos they didn't want to pay an extra 65p), then they "never arrived"
On that note, due to incredibly unreliable/untrustworthy posty's local to me: if you're not getting stuff signed for, get a certificate of posting from your PO. Doesn't cost anything extra, but if/when an item goes missing, it'll help no end with your insurance claim. Plus you can prove to the buyer you did really send the item. Remember bog standard 1st class post is automatically coverered to £28. An extra 50p covers the item to around £100 or £150.
Bare in mind some people don't want a signature as they know they won't be home and the local sorting office may be miles away...
Other tips:-
Wait until cheques clear before posting. They can still be reversed weeks later, but you'll at least know it hasn't bounced due to no funds.
Use lots of high res, clear, in focus photos. Host them on your own site, then just pu <img > tags in your desc.
Don't give negative feedback, unless its a very last resort. It can so easily descend into a bitching contest that'll mess up your own feedback just as much.
