I fill out the item specifics on my listings to give you as much information as I have. It is harder to find the item specifics on the eBay app. If you scroll down to where it says About this item you can click the arrow that is on the right side of the screen. That will take you to a screen that will show everything I filled out. Some of my older items may be missing this information. If you find a listing that doesn't have the information you are looking for, I'm always happy to answer questions.
I give a combined shipping discount for multiple books purchased from me at the same time. Magazines ship first class package if they are under 1 pound and either priority mail padded flat rate envelope or priority mail if they are over 1 pound. They do not combine correctly when you check out. You can 1) request a total from your cart, 2) contact me and I will help you with getting the correct shipping or 3) pay for them and I will reimburse any over payment.
