Ive had 2 this week like this show up to be built. Ive said it over and over, pinned posts, and even made videos on youtube and other social outlets over the years. From now on if ANY transmission shows up like this you will be charged a HEFTY additional fee for wasting my time and sent to the very back of the line. Its tax season and we do not have time for this let alone a tolerance for lack of common sense. Im done guys.

🚨📢EFFECTIVE IMMEDIATELY‼️‼️
For the past 20 years in business we have offered and held strong with 100% Free Shipping on all purchases. Due to sudden with NO warning changes to UPS policies and Freight policies are being hit with multiple surcharges... including but not limited to LPS (large package surcharge), stacking fees, increased fuel surcharge, zone charge, etc... these charges have totaled almost double cost on all shipments and i am unfortunately forced to charge shipping cost because of this to ALL units outbound. This news came with 0 notice and i apologize to you all.
Over the years we have always taken the hit for shipping in the name of good customer service and unfortunately that has come to an end. We have exhausted and explored all possible alternatives with no promising results.
All current orders and orders in process will NOT be charged and will be shipped back when complete 100% on our dime.
I am truly sorry it has come to this and this is not the FAFO Friday i ever wanted to post.
For any questions and concerns, feel free to Pm or call us at 888-744-6542.

We come to you from the teardown bench today and talk about a common problem that is still surprisingly not known about even today. Why a core ends up being a core most of the time - lack of understanding and poor modification.
