I emailed them and they responded withing 48hrs.

I was instructed to mail the pack to them. I'm sending it out tomorrow.

A month or so ago I purchased a GP motor that did not come with the caps and diode. They mailed them to me free of charge within 10 days.

With a giant distributor like GP, I feel like that is good service. To honest I was sceptical. They deal in such high volumes that I was prepared to be at the end of a very long list. Either they have a good number of techs working for them, or they work very efficiently, or both.

One thing I never do is sound angry in my requests. I always try to be polite and considerate. You see, I did a bit of computer tech support once and the angry emails got pushed to the bottom. When you're busy and the boss is bothering you and you're tired and hungry, the last thing you want to deal with is a troublesome client. I know what it's like to be in their shoes and I remember the people I was happy to help out.
