They should not cancel the transaction but the fact is that no-one can force the seller to sell to you, no matter what payment method you use.

If you are going to pick up the item it is really better for both of you if you pay cash when you pick up the item.  If it is not as described or you don't like it then you can just walk away.

If you have paid by paypal you then have to hope that you can get your money back by opening a dispute....and then wait and hope that the dispute goes in your favour.

I know what you are saying but online purchases, cash is the most secure.

You could pay with PayPal and turn up to the address with no one ever being home.

Could even be a false address by a scammer.

Cash is king. 

If you have a smartphone you could go to pick up and if all is as it should be make the payment using your phone on the spot or arrange to use the seller's computer to make the payment.

The seller is probably quoting the extra fee to try and discourage anyone for using Paypal to make the payment. It is not a god idea to pre pay on a pick up item from either the buyer or seller's point of view. Although Paypal no offer some protection with pick up it is not a sure fired thing that you will be able to get your money back if there is something wrong with the item.

I would never use Paypal for a pick up item and as a seller I would prefer for the buyer's sake that they paid cash after they had inspected the goods.

taking all advice given, maybe this seller is one to avoid.

if hes saying things in his listing that raise the hair on the back of the neck, might be a sign of a problem to deal with.

Never ever use PayPal for pick up items.

Sellers must also learn to never ever accept PayPal for pick up items.

All a buyer has to do is claim item not received and the buyer will ALWAYS get a full refund with no questions asked because the seller cannot prove the item was picked up/sent.
