The Mr. Jam Man Loyalty Programme

Buy 99 jars and your 100th is free.

Yes, really. We've done the maths and we're comfortable with it.

Your stamp card

Honour system. Tap a circle every time you get a jar. The green one is on us.

The small print

1. One stamp per jar. Jars must be full at time of stamping. We will know.
2. Returning the jar clean earns our gratitude, not a stamp. Gratitude is not redeemable.
3. Stamps are stored on this phone only. Drop it in the jam and they go with it.
4. Apprentice Harvey's decision is final, subject to bedtime.
5. The free jar will be whatever we've just made. It will be lovely.
6. Programme may be withdrawn if it turns out someone is actually on jar 98.
