When I did the lottery I was doing £4 on Wednesday and on Saturday, and only ever won a tenner on a very few occasions.
I decided I was spending too much for no return so decided to top up my Premium Bonds instead. At least you don't lose your stake and can get it back when you need to. I now have the maximum and last year got a 2% return as prizes, better than most savings accounts. This year has started of well and I've already got 4 x £25 prizes from the January draw.
If Camelot can pitch / twist the new (improved?) £2 lottery ticket to the ['gullible joe'] public, as a 'buy one get one free offer' ... then, they [Camelot] might be on to a winner ... only if Trading Standards allow it!
