bearmos shared a tip for free Digikey shipping in the US and Canada:
Here’s how to get it:
1. Add items into your shopping cart like you normally would (make sure you’re logged in when doing this). 2. Print it out.
3. Write a check for the total + tax in your area.
4. Snail Mail your order to them with the check (you’ll pay for the stamp).
5. When your order is received, you’ll get it via ground shipping, no charge.
This is actually in their terms:
6…* When a check or money order accompanies your order, Digi-Key pays all shipping and insurance (our choice for method of shipping) to all addresses in the U.S. and Canada.
