Here are things we've sent our grandson. (His school has long, cold winters.)
Beef jerky (most popular item)
Mac and Cheese cups
Soup cups
Microwave popcorn
Swiss Miss hot chocolate packets.
Cookies
Snack size potato chips bags
Beanie
Extra warm socks
K95 masks
Gift Certificates
We've found the easiest way to send money to grandkids is via their Paypal accounts.
For Gift Certificates, you can Google a map of their university to see which places are on campus or within short walking distance.
