I must confess that I am addicted to QVC in the morning - can't stand breakfast tv. Anyway they had shock absorber max (the one with the double strap) on clearance price of £21.60 this morning plus they are on 3 payments of £7.20 (plus p&p). All go up to a G cup. So if you can't afford to get a good sports bra this might be a good option or time to stock up if you shock absorbers are your fav.
Shock absorber max £21.60 - this is the one with a double strap at the back
Shock absorber classic £18.96
Shock Absorber max top - black £15.50 (not on 3 payments) - not many sizes left double strap at the back
