We bought a britax strider 3 wheeler pushchair, in january for our granddaughter, my daughter lost receipt moving house, the rear wheels on the pram are wearing uneven, causing the pram to have a wobble feeling to it, we went to argos for help and was told due to we lost reciept they carnt help us, so we asked abt buying new wheels from the company, was told they couldnt help us, we went to toys a rus and got more help from them, they rang round got a company name and phone number for us, but found due to this pram being exclusive to argos, they and no other company can get the parts either, help we need to replace back wheels as we dont want to replace pram as the grandson loves it
