There is a company store that sells luggage at TK... They give you a 20% off coupon on day 2... You can buy some pretty nice luggage cheaper than anywhere else... So hold off until you start.

slip on dress shoes or half boots with zippers will do the trick... Don't look like a slob and wear cheap shoes or black athletic shoes!

Uniform shop will let you deduct any extra uniform items off your pay check at you need to buy... You get a winter coat, suit jacket, hat, 2 ties, 2 pants, and 4 white shirts for free... Probably want to purchase another pair of pants or two.
