Hardly any 1.02-1.03 prices before the off. Usually just in-play.
Football is the best. You can decent 1.02's before the off. Sometimes more. For example, Liverpool play Newcastle on Friday. This fixture always and I mean always has goals.
The price for 1 or more goals is 1.07. That's 5 MORE points than 1.02. So in theory, if you bet on that game, you could do your entire 3 bets in one bet. Although you would be breaking the 1.02 rule. If it came in, great. But if not, you would be kicking yourself.
All you want is one goal. Nailed on imo.
