I do a few things to save money for our trips. I use reward sites and get US gift cards. We started in October last year and by our trip this October we will have made around $1000. (If you want more information on that PM me)
I also buy and sell Limited Edition Disney items and have made about $2000 since January. If all goes well this month, I'll make enough to pay off next years trip. Most of the items sell to US buyers so money is already in USD in our Paypal and we transfer it into a Disney savings account.
I collect my change as others have mentioned too but our biggest saver this year has been changing the way we shop.
We used to spend around £130 a week on grocery shopping and I decided that I was going to get that down to a maximum of £80. I started paying close attention to coupons and what we were spending our money on and now we only buy what we need for the week and spend the rest on "stock pile" stuff which is on some sort of deal. I have cut our weekly shop down to £80 a week and now have a stock pile of stuff that we got for half price or less that will last us way beyond our holiday. We won't need washing power, washing up liquid, cleaning supplies, toilet paper, deoderant, shower gel, shampoo, conditioner or canned goods until 2014! It's amazing how much money we were wasting. The extra £50 is saved and used to buy USD.
We want to do a couple of boot sales soon too, we just never seem to get around to it.
I banked £400 today.
