Who get's the the boot?

After recently starting my first job at topshop (of course im going to brag!), I'm trying to work out what i will spend my two months worth of pay on, after doing a bit of window shopping as you do in the "recession" i have recently fallen in love with 3 pairs of army style lace up boots, its so hard to choose between them all, i know they may look the same but believe me there not! i have tried each of them on but still haven't come any closer to a decision, any help?!
