Does the 420recs app really work? Will they let you print a certificate you can use that day or an id card to use same day??

I'm not 100% on 420Recs cause I've never used them, but NuggMD will work same day and give you the option of print out or just show your document off of your phone so they can see your rec ID number. I've used it this way, same day that I purchased it. Only cost 39$ and was so fast and easy, I've gone back every year to renew with NuggMD.

Idk never tried them
