I usually ship twice a week when I've got a few items together and I expect payment immediately on winning an item but 7 days is my absolute limit.
SHIPPING has to reflect the true cost of the entire operation, not just the postage cost itself. The culture on eBay seems to be one where people are happy to pay £6.00 or whatever to concert ticket agents for two pieces of paper to be mailed to them. Well - I'm not a huge conglomerate, I'm a person in a front room so please don't kick off if there is a difference between cost price of postage and the charge for P+P. If I sell a record for £2.50 and charge £1.50 on postage but the stamp is £1.00, the 50p difference is more than taken off me in other ways - from eBay/PayPal fees, and my time, petrol, packaging materials that all cost money - it's ALL part of it. I come out with mere shrapnel and even then it's by pure chance - I calculate the cost of the P+P in genuine good faith.
Any return is at the buyer's expense but a full refund will be given if not satisfied.
