It's nearly time to go back to school/uni, so what better excuse to look for a new satchel (even if it's only your kids going back, and not you)?
Oasis as usual have a great line of leather bags, and this Colour Block Thatcher Top Handle Bag is perfect for transporting your documents, books and stationery/laptop. It's got a shoulder strap too if your load is too heavy to carry.
At £30, it's means you shouldn't have to break into your student loan to purchase it.
