I have been using this plugin for the past month, but I am having difficulties with the postage pricing. I have a website that sales women’s clothing and most of my orders ship out using priority flat rate envelopes, in which i usually pay approximately $6. I have set up all of my products with very minimal weight and dimensions, since I can usually can fit them all in an envelope, but when I get an order with more than one item, the shipment label that is created is charging me $33 . I’ve been having to ask for refunds directly from Easypost, but it takes 30 days. I am not sure why it is do, but as for a refund.
