As far as I know, the discount is directly from 80/20 not the distributors or at least that is what our distributor has always told us. Your distributors may not be aware of the discount from 80/20 for FIRST teams so you may have to politely ask them to check with 80/20 directly. The discount is a little less this year than in the past from what I understand. Our distibutor quoted us 34% off list this year rather than the 40% it has been in past years.
