Iām trying to understand Amazon FBM shipping costs and wondering if I may need to adjust my shipping template. I recently shipped a 7 oz item in a bubble mailer to a nearby state for about $5, which seemed reasonable. The next day, I sold the exact same 7 oz item, also shipped in a bubble mailer, to a state only one state farther away, but the shipping cost was around $9. What confuses me even more is that Iāve previously shipped a 2 lb item in a box to one of the farthest states for about $10. Why would a lightweight 7 oz package in a bubble mailer going to a relatively close state cost almost the same as shipping a 2 lb package in a box across the country? Could this be related to: - my shipping template settings, - delivery promises/transit times, - carrier selection, - or something else?
