I have been to the Lombard store, just bring a copy of the RD coupon from KCBS and they will let you in. I believe they even told me as long as you show them your membership card then you don't need the coupon. As for Tri-tip.........That is a BIG YES. the only other place I can find it besides going to my local butcher, Butcher on the Block. They sell the tri-tip in cases. I had 5 tri-tips in mine not sure if it varies.
You will love the place.
