I've had two grocery store butchers around me tell me that "sirloin tip roast" is the same thing as tri-tip. I bought a couple, and they are obviously thicker than the tri-tip shown on the web site here.
Can anybody confirm whether that's right or not? CostCo has tri-tip pre-sliced, but won't sell it(?!) whole.
