Simple Delivery charging wrong postage cost

[lansmalqui]

I have the predicament caused by ebay's backward, sorry, 'Simple' delivery that the postage doesn't cover the service of combined items due to a weight increase. I will be charged the extra, plus £10 for not using the correct service. It's happened to me before (though they increased all the dimensions to pursue a fine) I don't know how to avoid it, other than cancel & start again... Not 'simple' at all...  Why have they taken control away from the buyer? Should I just go ahead & hope I don't get charged extra, as it's not my decision to charge for the wrong weight. ?

Don't combine if it means the postage is incorrect.    It's best to cancel/refund the transactions with the buyer's agreement and relist with items on one listing and a single postage cost for the buyer to buy and pay again.

Hi. OK, thanks. Yes, the only option to avoid extra charges. Shame not allowed to send an adjusted invoice if several items are won.
