From the Tampa Bay Lightning press release from last week:

Along with Metropolitan Ministries staff and volunteers, families of Lightning players will be accepting donations of non-perishable food items on Ford Thunder Alley starting at [...[ 5:30 p.m. prior to next Saturday's match against the Minnesota Wild. For every 10 food items donated, the donor will receive a ticket voucher, with a max up to 4 per person, redeemable for either of the Lightning home match-ups on December 4, 9 and the 11.
