I was shopping at Costco and couldn't believe it. Most likely, a price mistake as it said regularly $9.97 less $5.00 savings at checkout. 60 count K-cups of Starbucks French Roast for $4.97. Limit 5 per person. I bought 5 and there was one box remaining. Please see the picture attached. When I got to the register, I asked the cashier to verify the price before ringing it up. Even his eyes lit up once he verified that it's $4.97.
For reference, it's listed at $37.99 online:
Of course, this is a BIG YMMV. This was at the Inglewood store in Los Angeles. This may be awfully hard to replicate. Just saying that if you go to Costco, keep your eyes open in the K-cup section.
