Not Able to Place an Item in My Cart.
To fix the issue preventing you from adding Office to your cart, first trying opening up the online store in a new incognito/private window
SHORTCUT: (PC) Ctrl + Shift + n (Mac) ⌘ + Shift + n
If you are still unable to add the product to your cart, try a different browser, I would recommend Google Chrome or Microsoft Edge
If that also does not solve the issue, clear your cache and try again.
