Hi - I’m selling an expensive piece of golf equipment on EBay, the buyer has made an offer but wants me to post it to them. It’s listed as collection, I’m happy to post but I want to be sure 

A) I get my money before posting it 

B) I’m not liable for any damage in transit 

I’m concerned because it’s technology over £4,000 but the buy lives in Northern Ireland and I’m in England 

can anyone advise? And will it incur import taxes etc?
