Are the extra costs worth it?

Great app which helped my game a lot. I paid $4.99 for it. But with the recent app upgrade, I have to pay an extra $4.99 for HD + $1.99 for 28 indoor drills. That part I dont agree with! Im sure Paul makes enough money and he really doesnt need my $7.00. Its almost worth a delete from my phone!
