well i've mentioned it on the other thread but here goes:
*trendy clothing and accessories- those tops/earrings/nail polish that you just *know* are not going to become classics and you will wear for one season.
*nice looking but cheapie shoes i wear only around my office - i leave them at work and wear sneakers to/from work and change when i get to work. sometimes i luck out and the shoes last more than one season but since they're so cheap, i don't care if i throw them away. (i will not cheap out on the sneakers, since they're my "vehicle" - i don't have a car and walk a LOT).
*buy classic clothing at end of season sales - slacks, jackets, shells, boots...
When i'm traveling, it's more that I'll use the money I save on hotels and airlines for other things (shopping and museums). i've stayed at cheap hotels and even youth hostels (private rooms but shared bathrooms). if it's a choice between staying at a nicer less expensive property near newark airport or staying at medium range hotel for double the price in manhatten or the YMCA in manhattan - the Y won out. I only use the room to sleep in, i'm out at the crack o' dawn, and out all day, plus it has a pool which most NY hotels do not. same with airlines - I haven't yet flown on the real "low cost" airlines, but medium range ones (even less space in coach, no personal screens, terrible schedules) - it saves me ~300-400$ per trip.I'm not big on eating in restaurants, so again I'll have pizza or a big salad and keep going.
