If you decide to go USPS, make sure to go to an actual post office. I went to PostNet to mail a quilt and he said $17 (after I had checked the postage online - $7). I asked why, and he just kinda shrugged. I said no thanks, since I had mailed a quilt a year ago and I know it wasn't that much. I went up the street to USPS, $7. And I mentioned that to her, and she said that's all overhead. I never even thought they would add overhead, and $10?! So, point being, if it's USPS, go to a USPS location.
