I received an inquiry as to who is eligible to pay exact shipping, which means you pay me the sub-total first and then a second payment for exactly what it cost me to ship after I do so. The following people are eligible, and sorry I can't be too flexible on this:
1) Those with 50+ feedback at
100%.
2) Those I have traded with extensively AND trust (not that there's anyone who's one and not the other)
That said, regardless of your feedback if you pay more for shipping than it ultimately costs me to ship your items, I'll refund you the difference. If it costs more to ship than I charged you, then I eat the cost. It's win-win for you. For this reason, those with very heavy or bulky items might find their shipping charges higher than expected, but I promise
you will not ultimately be paying more than what it cost to ship your stuff (within reason, I'm not sending out a bunch of $.50 refunds

), so even if I overcompensate for a heavy item (The .hack boxset and the DA:O guide are the heaviest) you'll get that money back.
Let me know if there are any questions on this.
