From nonsmoking home. Thank you for buying from an individual on eBay (instead of big—often Asia-based—companies). You touch a home when you do! I make shipping as low as I can for you; it is not possible for individuals to offer Free Shipping, as much as I’d love to. Mail carriers keep raising prices. I will combine shipping with other items I have listed, so if you purchase multiple items from me—wait to pay—I will send you an invoice with the discounted shipping cost. Also, in respect to the environment, I reuse boxes and packaging materials. Thanks for looking through my items!! :)
