Do you love to go shopping, but seem to spend all your money on just one or two items? If so, why not consider hunting around for cheaper, second-hand options? With a little time and patience, it’s possible to find some great bargains. Take a look at the shopping alternatives we’ve come up with. Car Boot Sales People bring unwanted things that they dig out of their attics and garages to a car boot sale. Anything from children’s toys to sports equipment can turn up at these sales, which are usually held at weekends or on Bank Holidays. Second-Hand Shops Good second-hand shops can be full of surprises and are often the perfect place to pick up a bargain! Many shops often specialize in certain items such as rare books, designer clothes and antique furniture. Charity Shops People donate used clothes, shoes, toys and other different items to charity shops where you can usually buy them for next to nothing! The money often goes to help people who are hungry, homeless or who live in poor developing countries. Christmas Bazaars These are wonderful places to buy handmade gifts, Christmas decorations and second-hand items. The beauty of these bazaars is that all the money raised usually goes to charity, so you can shop till you drop knowing that it’s all for a good cause!
