Argos have a small selection of Baby / Toddlers / Kids toys in a 2 for £10 promo at the moment. Admittedly some don't have much of a discount in the offer ie £5.99 each or 2 for £10, but some are really good value especially the Little Tikes Cash Register that seems to be £15+ elsewhere (Tesco, HOF, Amazon etc). Little Tikes toys are always incredibly sturdy & they'd make fab Christmas / Birthday Gifts. They also have a Chad Valley My First Dolls Pushchair £7.99 each or 2 for £10 & various baby toys at £6.99 each or 2 for £10.
Link should go the cash register & under special offers you have the chance to choose which products you want in the offer
