I dont like bait and switch. Went in today for an oil change, had a coupon for 54.99 for 5 quarts full synthetic, I knew it would cost about $7 more because my jeep takes 6 quarts. From the beginning the guy kept telling me its $10 off, even though the coupon said $54.99. He said he had to call and order the oil, and while he was on the phone he told me the oil was going to cost $60. Plus $8 for a filter, plus labor. So, I again referenced his coupon,and he said it's only for $10 off. I asked him to show me where it said $10 off. He said it doesnt, but that's the intent.so I choose to leave.if your go in ng to send out a coupon to get return business, then honor it.
