Membership renewal

I was getting ready to renew my membership today and discovered that if you send the money via the envelope supplied in my magazine it is $41.00
Now if I renew online it is $36.00. I want to order some of the new graders and want to send my money but how much should I add for a first class delivery?:noidea:

not sure about the envelope but dues do increase starting Dec 1st.
You can call the office on Monday to order the items you want and get your membership questions answered.
If you call you will not have to buy a stamp!

Here are the notes from the BOD meeting:
The increase in dues will take effect on
December 1, 2011. Marketing materials will be adjusted to reflect the
membership dues increase.

Amount to Increase:
US Standard $5.00
US First Class $5.00
Canada, UK, & Mexico $7.00
All other foreign $10.00
