there are different styles in toys r us. one is $249 and anther is $299. one of the style is cheaper but I'm not sure the price.
the brand is 'Safety 1st' - portable booster.
the difference is $299 one can 'folded' like a handcarry box. the cheapest one can't be folded and no 'tray' at front. I hv both '$249' & '$299' - one at home and one for my babysister used. both are good. but seems not all the shops hv this items. you better check with the shop by phone before you go. hope you can get it.
