OK, thanks for getting back to me. I’ll do some research before I activate my 2nd mini. I’m guessing that I might have to create a 2nd Walmart account but hopefully not.
After doing some reading at Google Express support FAQ which states:
Can my family members also link their accounts to get the discount?
The promotion is limited to 2 per household.
Leads me to believe that you do need two separate Walmart and Google accounts to be linked to get the 2nd $25 promo credit.
Also, be careful when linking accounts because they can’t (or won’t) replace the promo code.
I linked the wrong accounts – can you cancel it and give me another code?
You’re welcome to unlink the accounts. However, we can’t issue a replacement promo code.
