Ebay, please teach users the difference between ADD TO CART and BUY IT NOW

Venting as I combine multiple orders from multiple buyers, over and over again. Create a video tutorial that pops up the second time a buyer selects the same seller in a row. 

Please Ebay, add a feature that prompts buyers to use "add to cart" feature when buying multiple items in the same 24-hour window. 

Please combine orders from same buyer automatically. 

Also, the bulk shipping tool still can not create a combined packing slip, only a clunky "pick list" not intended for buyers. 

RANT OVER

It's not in eBay's interests to have buyers use the cart - separate orders generate additional "per-order" fees.  And there's no way for eBay to know that you, as a seller, actually want separate orders from the same buyer combined - what if you've already shipped one of the orders, and then they combine it with another order?  Answer: you're out the additional shipping charge.
