Too many items in cart

[2007gregi]

When I pressed commit to buy, nothing happened so I pressed again. Now 2 items in my cart. Can’t delete. Only want one

Go into the cart and there is a remove option for each item.

The OP probably can't remove either of them if they pressed "commit to buy".

They will have to contact the seller explaining their mistake and request cancellation of one of the items - which, as you know, the seller is under no obligation to agree to.
