For those of you who are curious abut the math -
The 10 item sampling lanyard works out to $4.20 an item
The 5 item sampling lanyard works out to $5.40 an item
So unless you use the sampling lanyard to get soda / water it will be significantly cheaper to get the 10 item lanyard. Soda / water are cheaper to pay cash unless you are just using up a last punch of a lanyard.
