Our Last Trip to London & How We Saved Money Through TopCashBack UK! On our last few days in the UK, we just discovered about TopCashback UK! Where you get a money back on online shopping, booking hotels and even booking the train ticket! TopCashback UK contacted me to check out their website and I’m really glad I did. It’s like a normal online shopping which makes it that much easier to use, and it’s great making money back on something I was going to already purchase!
