Hi

Im working on improving the reorder function. I will share when Im finished.

 

My challenge is:

how do i merge two carts content? 

Lets say I have

$cart1

and

$cart2

 

And I want to add products from $cart1 to $cart2,

and then delete $cart1 (i think thats just $cart1->delete() isnt it?)
