Hi all, Starting January 17, 2016, the USPS increased postal rates as much as 16%: http://blog.stamps.com/2015/10/22/usps-announces-postage-rate-increase-starts-january-17-2016/ Pro Audio Engineering will hold our Priority shipping rates at the old price until the end of January. Thank you! Howie - WA4PSC www.proaudioeng.com
