Re: If I do this I should be fine right? I have one question
you can use USPS click and ship for a shipping label and use your own address as a return address on the label. But it gets complicated if they want to return because when you buy another label for the return and send it to the buyer they have to ship the item on a certain day, the one you decide on. USPS gives you the option of the day to ship on, you can choose the day you buy the label and any one of the next 4 or 5 days. but its only good for those 24 hours of that day. The buyer can ask to meter the label which will make it good again at the post office if they miss the day to ship, but it will change the tracking number.
Your best bet is to open a shipstation account. You get a month free plus $10 free shipping from stamps.com. then you can use your address as a return address and if you need to send the buyer a return label you can and it will be good for 5-7 days, not sure which it is though. shipstation will email it to your buyer and you upload tracking into ebay.
if your running a stealth account shipstation is a must. it will save you money in the long run. |
