I would personally be quite fine with paying that number, works out to 6.25/fp. But what's important is your market. Are you one of the only sources of FE goods around? Then you might be short changing yourself a bit. Are they a guildie and it's an arc which helps the guild? Then maybe it's fine to be more giving. I was doing multiple trades for TE goods at 5/FP and everyone was happy with this number. The few amount of people still in the era or with left over goods (so I didn't have to delete half my friends list) meant I wasn't going to shop around I was perfectly happy offering a bit more to get goods from what to me was a limited resource pool.So it is a good deal for someone. I am not ripping them off.
