You've got to save wherever and whenever you can. Be it at the supermarkets, on your commute to work, or on the holiday itself, you need to search around to make sure you bag yourself a bargain.
If you have a date and destination in mind, sign-up for emails from travel agents, airlines, and hotels and get ready to pounce if an offer lands in your mailbox.
Make sure you regularly clear your cookies (not the edible kind), cache, and browsing history; retailers can sneakily use their algorithms to target you with higher prices if they know what date or destination you're looking for.
