I tend to place orders, and then due to customs inspections and the different delivery speeds of different couriers they arrive sort of staggered rather than all in a one-er.
I get asked the question every now and again, and to be honest yes I am lucky in that I can afford a fair bit of airsoft stuff, but trust me, most people wouldn't want to be me. The main reason I have expendable income is because I don't have the food and accommodation bills your average person has. I live in the barracks, and yes it's criminally cheap and perfectly liveable, but my room is smaller than a 'studio' flat so I can't actually store my airsoft gear/guns there. 98% of it has to stay at home and I only actually get my hands on all this kit I buy for a day or two every few weeks. Often 3-4 months go by where I don't get the time to come home with work and social commitments. Also having someone else decide what you eat every day, and then get it made on a shoe-string budget means I don't exactly spend my time wishing for the next meal, heh.
Not that I'm bleeding my heart out here, there's guys in the army who spend 6 months in afghan every 18 months getting shot at for a far lower salary than I'm on. I'm in a job where I actually have to put a lot of effort in to try and get selected for deployment, and if I were to go out there, apart from the odd far away rocket, the major dangers would consist of boredom and eating too much Subway.
