Choice grade beef tenderloin for $10/lbs from Arabic market, is this sketch?

Seems way too low a price. It was vacuum sealed, silver skin still on. The meat looked fine enough, Im really just planning on making kebabs tomorrow and was looking for top sirloin but they only have tenderloin and some other not so kebab-friendly cuts so I said fuck it. I guess I'll know for sure tomorrow when I open it, but I just am so curious how they are selling the cut for so cheap and if I just bought low quality meat or what
