I have 7451 Avios and can do nothing with them.

The photograph was taken in Westfield Stratford, It shows a man who has too few Avios to spend on anything useful.

There is nothing quite as useless as a small number of Avios and one should either collect them seriously or not at all.

The easiest and best value way of collecting them is probably Tesco. Their £3 lunch deals are good value, £10 'finest' meal for two is even better but almost always has a sugar laden pudding included.
I am also buying cashew nuts and almonds as a snack to eat while working. This boosts my spend a little too. £250 translates as 600 Avios which means a crate of wine every 16 months. Not bad, and they make good Christmas presents.
