I use reverb safe shipping or RSS for all purchases, it’s fairly cheap, unless you charge Crazy prices, especially for them to be there, to deal with, and quickly resolve any and all issue., usually in a matter of days. This service is less than $10 for items between $200-$400, to give an example. We are also sometimes offered shipping discounts with some services, if possible I like to use my discount to try to upgrade my buyers shipping. Anyone that charges $100 for shipping and says they lose money on shipping, it’s only because they’re insurance value is so high with Reverb services, if they didn’t charge $2000 for a $700 item then they’re shipping prices would be just fine. All you’re paying for is a higher insurance value, if my items are described to work then according to the description you get a working item or your money back. Thanks for your support, ALL my items GUARANTEED to work as described. I pack well and ship multiple times a week. Good service should not cost an extra thousand dollars an item.
