A Case Lot Party?

This apostrophe typo arrived in an email about my company's upcoming Christmas party:

Live Band, delicious hors d'oeuvres, games, excitement, lot’s of surprises, and great shopping!

I forwarded it to Mynamyn, and we had a small conversation:

Me: Please disregard HR's apostrophe typo in "lot's of surprises."
Her: We were wondering if the surprises come in lots. Like, a "lot of 12." It is Costco, after all.
