These simple yet effective life hacks aren’t just time savers, they’re also money savers too. Take the post-it life hack for example; no need to spend money on fancy tools to clean those hard to reach areas, just use an old post-it note to get the job done! Another great life hack is the toasted sandwich idea. By placing two slices of bread in a single toaster slot you can create the ultimate toasted sandwich. Never again will a BLT be the same!
