I happened to check my amazon assistant plugin in ... Morechrome today (mostly to clear out the old messages and remove the notification numbers, but i digress) and noticed I had a $3 off of 10$ "back to school" promotion. I do not have a link to it as it disappeared from my list after I clicked it. It says that I have 18 days to use it.
To test it out, I added some random item sold by amazon via the assistant (my go to item is nutramax cosequin). I saw a $3 assistant credit when I went to check out.
the really cool thing was , after i removed that item from my cart and then just added a random item sold by amazon (not via the assistant), the $3 credit remained. I think I remember it doing that the last time i had an assistant credit. Anyways, I am not sure if this is showing up for everyone, but hopefully it helps someone. To find it, click your amazon assistant button in your browser, and it should be right at the top if you have it.
*EDIT* It appears that someone has kindly added the link, thanks!
