The scenery above and behind the bushes along the side of Betty Jo and Steve's cottage doesn't match up when viewed from out front and from inside. This can easily be seen when Kate gives Betty Jo the present from Mr. Bedlow on the porch then walk in the house.
The display Kate knocks over with the cart is a stack of gallon size cans of puffed wheat. Unlikely that puffed wheat would be packaged in that manner.
