I started my "lunch on a budget" program with a co-worker on January 3rd, which prompted my Latte Factor posting.
The objective: To bring lunch to work everyday.
The incentive: $150.00 shopping trip to Seattle after three months.
The punishment: Each time we slip, we have to deduct $10.00 from our shopping trip.
Progress
Me:
Days so far: 10
Money saved: Jan 3 - 16, 10 business days x 10 dollars = $100.00
Money deducted: I slipped today, and bought a gello $1.45, so $10.00 deducted.
Trip money: $140.00
My friend:
Days so far: 10
Money saved: not sure, because she slipped quite a bit.
Money deducted: Not only did she slip > 10 times, she also decided to shop before the trip :(
Trip money: $0.00
So, it looks like I will be doing the "lunch on a budget" program by myself!
