I would love to get thoughts on etsy plus, is it worth it? or leave it on the normal account and then down the line get esty plus. What does everyone think?

Hi everyone, this might me stupid or gone over before but how do you charge? I notice etsy offers different prices for UK, USA and then ROW. But PrintShrimp offers major different prices for example Canda is £9.49 and South Africa (where im from and where friends and family will order from) is £4.99 and theres no way to make those prices different. These prices are for an A5 print. For Etsys ROW would i make my base cost 9.49 and add my mark up on top of that and if someone orders from South Africa i just make a lot more profit? Has has everyone else priced their posters using PrintShrimp? Thanks!
