My team has recently had issues using the $50 Digi-Key voucher and I’ve found the solution:
DON’T SIGN IN TO YOUR DIGI-KEY ACCOUNT!
So every year, each team gets a $50 Digi-Key voucher. The process explained on both the FIRST site and the Digi-Key site is just “click on the voucher, enter your team information, and shop/make an order.” They then say that “The voucher will not display on the total of your order, but will be subtracted from your order during processing.”
While the dollar savings of the voucher will not be displayed on the checkout page, it will be obvious if the voucher is working, if you do it right.
If you have an account with Digi-Key and already have items in your cart, going through the voucher page will take you to a blank cart, where you will then maybe try to add the items you had in your normal cart in to (what you think) is the special “voucher cart”. But then you will see that your existing cart merges with this special cart so you have to remove duplicate items. Then, keeping in mind that it says “the voucher will not display…” you complete the order using your saved account information and hope for the best. This will not work.
Instead, clear your cart (export the list of part numbers or write them down), log out, then maybe even clear your cookies. Then, go to the same digikey.com/FIRST page and enter in your team info like you did before. This will again bring you to an empty cart where you add items. Once you go to check out, you will notice a few things different. Instead of prompting you to log in or create an account, it will autofill a company name of “FIRST ROBOTICS PROMOTION” and also fill your team info into the “order notes” section. Then, when you place the order you will get a confirmation which, again, doesn’t show the voucher. Although, at least in my case, there is a little ad blurb at the bottom of the confirmation saying “Proud to supply your FIRST Robotics projects, Digi-Key looks forward to supporting your next project too!” In theory, you should get a corrected invoice in a few hours or a day which shows the final total taken from your credit card. I didn’t, but the packing list shows “MISC CREDIT OF $50.00 FROM FIRST ROBOTICS PRODUCT DONATION VOUCHER. CHANGED SHIP METHOD TO FREE 2 DAY.”
