Re: postage error
Have you checked you have sufficient available balance?
Note - if the PayPal is new, any inbound payments are most likely going into the 21 day hold (whereby you need to wait 21 days before the funds are released).
If it is the case, I suggest you use alternative methods to fund postage in the meanwhile (i.e. paying over the counter at the Post Office).

Here are a few things that will help reduce your 21 day holds down to about 5 days:
* Shipping item out on time.
* Submitting valid tracking information to eBay and PayPal.
* The buyer leaving a positive feedback.
After approximately 3 months of doing this, your holds should be removed. However, just because holds are removed doesn't mean you're in the clear as they can return at any time. |
