I do combine shipping at cost.This is actual postage plus shipping materials. Please note, you have shipping options available to you under the shipping tab. I try to reuse as much as possible to save. You must let me know if you are watching or bidding on another item. Do not pay until you receive a combined invoice, so you can get the discounted postage. Positive feedback is greatly appreciated, thank you. If you have a problem, please, please, check with me first. I will do my best to resolve it. I'm a senior on disability, and I do make mistakes, from time to time.
