We never buy from sellers using this option.
We ask if they will send without using the GSP and if yes will continue with the sale, but many say no, so we then move on to someone else. As someone else, said time to talk with the seller is before buying.
Many sellers don't even realise how it works, ie that the buyer has another charge added over and above the sellers postage cost, so giving them a bad feedback is a bit hard, of course many have no idea how to opt out of this function. If the seller can't or won't remove the GSP function, just move on, you have had a hard lesson thrust on you, is it right? legally yes, but ethically probably not.
Don't worry we have had it too, and boy did it make us sit up and take notice. This is now the first thing we look for in a sellers listing, and the item would have to be really worth considering for us to keep moving forward. Mostly we just click "next"!! and we are probably not the only ones doing so.
There has been streams of complaints and comments on the discussion boards, about this function and nothing changed so you really have to decide if the item warrents paying the extra. Sometimes you might pay and sometimes not, but at least now you are fully aware of the possible consequences, sorry that you had to go through this but please don't stress, life is too short.
