I have done it a few years running now. After christmas all of the chocolate coins go for 10p and the chocolate Santas and reigndeer are 25p so I buy enough for my kids and other children's I buy for.
I check the dates and last years say they are okay until April 2020.
It saves me money and it is in date.
I was just reading another thread about someone buying their advent calendar a year ahead and I honestly thought it was normal (at least for lower income families.) But now I am not sure I should be gifting year old chocolate. No one has noticed but then again I haven't told.
Would you think it's disgusting? Or is it fine?
