Do you purchase movies, cd's, games, other media from 3rd Party Amazon sellers?
If you do, Amazon has quietly announced they are increasing shipping rates for the above from $2.98 to $3.99 for 3rd party sellers. By quiet I mean I haven't heard about it yet so this could be old news.
Amazon doesn't explicitly say they will increase the costs for buyers but does mention the shipping credit is increasing. Normally this would mean the buyers will pay more for shipping. The new credits/increase will go in to effect April 24, 2013.
Thought I would give everyone a heads up since I just heard about this myself.
