Regardless of whether the buyer is a novice or didn't see the questions and answers because they may or may not be using a mobile device, it actually quite clearly says pick up where it refers to postage. I am not on a mobile device but can see it mentioned twice and then a third time under questions and answers? I would be surprised if mobile devices/apps left pertinent information out completely.

Seller should not have to worry about chasing around and getting quotes, they shouldn't even have to worry about packing the item which is another issue all together.

The seller could always suggest the buyer arrange someone to pack and collect the item at the buyer's own expense. Even suggesting this is going above and beyond, seller specified pick up only for a reason, his item his rules?
