The lowest priced bikes here are balance bikes for £24.99, available in green and pink. In terms of 'normal' bikes, they are also selling the 12" Rocket* or 12" Glitterbug Bike* for £29.99, which seems a good price - it looks identical to one I saw in a shop for £65 last week!
At the other end of the scale is the 24in Procycle Sonic* bike for £199, reduced from £299.99, this bike is made for easier cycling and more speed, with a front zoom suspension to offer comfort and control when travelling on rough terrain.
There aren't as many sale scooters, but the Evo Pink Move n Groove Scooter* is on sale for £9.99, which I think is a great price!
Hopefully these sales will help you save some pennies on the bigger presents under the tree!
