I apologize for the lack of communication. The coupon clearly states up to 5 quarts of synthetic oil. The extra pint cost an extra $1.50 and your filter was an extra $2. The coupon sets forth that shop supplies are $2.40 and that tax is extra. Sincerely we have no intention of ripping anyone off on any service. If you want to stop by, I will personally give you the $3.50 out of my wallet.
