Just got a mesaage from Paypal saying I owe money for underpaid postage. That is the first one I have ever received. I checked if there was ever a problem with this on this discussion forum. Looks like this was happpening quite a bit back in 2017. Anybody else have this problem lately? I am always generous with my measurements & weight. I always add extra just in case. And the funny thing is this was not for a sale on eBay. I sold something on Craigslist, the person paid with PayPal & I shipped the parcel to his place in B.C.
