When Ted misses out on stuff at the beginning of the episode he says "Aw man." A reference to him being the blitz.
In the DVD version of this season there was a commentary on this episode, recorded by Ellis Duncan and Evan Rock, who were two actors who had filmed a scene for the show, which for some reason was not in the episode. They did not know this prior to the commentary and found out while recording when the characters they spoke to left the setting their scene was at. They even waited until the very end of the episode, hoping for some sort of tagline possibly explaining what happened or whether or not it was a joke.
The name "Price Co" serves as both a "bland name" for Costco, and a nod to that chain's history - it merged with another wholesale club named "Price Club" in 1993, a few years before when this episode is set.
