Due to a 'glitch' in their discount calculations at checkout, Tesco seem to be offering 20% off the original price of their toys that are already in the sale.

I have rather anally bought a load of bargainous Christmas presents such as:
Kung Zhu hamsters for £3 (£10 RRP, £5 in sale plus 20% off RRP)
A perfume lab, Bendaroos kit and Downfall game for £3.90 each (originally £16, reduced to £8.50 then 20% RRP: £3.90
)
Paperjams drum and guitar kits for £7.50 each
Overall bought £393 worth of stuff for £160 - and got 458 Clubcard points (?!)
