I want to buy several bottles from Campfire Kitchens, how do I do this on e-bay and have only one shipping charge? I'm not seeing a way to add items to a cart..
Put a bottle in your cart - when it asks you to Pay Now, choose 'keep shopping'. Repeat as often as you need to get the flavors you want, and the last time it asks you if you want to pay now, say yes. It will take you to a page that details your charges. If the site has shipping charges 'per bottle', choose the option to 'ask seller a question' - then ask if they have a combined shipping policy and ask them to send you an invoice. Then wait for your invoice and choose to pay it - you should then see the reduced shipping charge on your set of items. Then pay.
I buy clothing on eBay and when I see something I like, I'll look for other items from the same seller and see if I can get combined shipping - the seller may say so on their 'item' page. Sometimes the 'pay' option on eBay shows the combined shipping, but sometimes you have to go the 'ask the seller a question' route to get a combined invoice to get the savings on the shipping.
