Used will call for the first time, was super convenient and easy! Only problem is I get home to open my bag and find 2 half empty cartridges, so I drive back to ask why and exchange them . The “manager” told me that they could do nothing and that the state regulates and fills their product and he could promise it was .5 G and if I didn’t like the product not to come back again. What awful customer service, loved this place till today won’t be back and don’t recommend anyone buying medicine form them!
