Core charges are not about the money. Money changing hands is the LAST thing in our minds. Injector rebuilders like myself would MUCH rather have your cores than your money. I wish people would get a grip on that rather than bash us all for our core charges. We don't even charge the core fee up front. You have more than enough time (30 days from the time you receive the injectors) to get them back to us before you get charged. If we wanted your money that bad we'd charge it up front with the purchase. Some of you act like we are out fvcking everybody out of their core money, when in fact it is the exact opposite. We have NEVER had to charge anyone for cores. If you don't turn the cores in before 30 days we assume you are keeping them and your card is charged. Plain and simple, we can't make money on your money. We can make money by rebuilding your cores and providing them to the next customer. If you don't turn the cores in, then we have to take the time to go find more cores to replace them with.
