The USPS just had a postage increase on 5/14/07, last Monday. First class
went up by about 5 percent Who uses first class in shippng Vanagon parts?
( I do. My  36 piece stainless steel exterior set ships out first class )
First class only goes up to 13 ounces.

All other USPS services and products were affected,too. First class was
just a teaser rate increase. Here are the affected services that affect me
( and you ).  Economy parcel post to Canada has been eliminated.  Priority
mail is the cheapest way to go, now. Priority mail has increased 13
percent. Delivery confermation has increased from 50 cents to 65 cents.A
30 percent increase. All the other services have all had increased beyond
the 5 percent first class increase. www.usps.com  or  1-800-275-8777.

Im still getting aquainted with them. I sold several items to Canada this
week and the recipients are all choking on this shipping problem.
