haha on this question, I will say it depends on several factors. If you are just starting out, you may spend more. During certain times, there is sudden splurge of many new stuffs that you want. After the bills how much you can spend. I have to pay twice the amount $20=$40 coz my currency is not USD =( If the items go on sale, special promotions, value for money packs also grab my attention. I noticed that many vendors are lowering their prices for the new products which I think is great coz it allows me to purchase many more stuffs :) Mostly it average $100-$200
