Mamya it's the "drops them up and down the path" bit I was addressing. If the bags were dropped at the front door they might not need to buy a trolley because they wouldn't have so far to carry them.
I shall say no more, I was trying to be helpful.
I'd phone afew neighbours and see if there are any mums with a redundant baby buggy that they could either sell to you or even give one way.The straight up lightweight ones.
