Hi to all having issues adding items to cart. Called customer service today (Friday, March 15). I was having the same issue as I wanted to purchase multiple items from the same seller. I had nine items in my cart (all the same) and 100 items saved for later.
Customer service had me delete some items from my saved for later list. I was then able to add additional items to my cart. Apparently something has changed with the cart. You now can only have 100 items between your cart and your saved for later items.
Give it a try...maybe it will work for you!
