Savers might still be doing 21 packs for £2.99, so just over 14p per tablet.
Amazon fluctuate with offers and can be cheapest. About 17p each for 100 right now so slightly dearer but maybe helpful to you.
Waitrose is cheapest at the moment. 100+ tablet packs @ 15p a tablet
Any ideas where the best place to get these from normally nationally?
Very good spot for a store specific deal.
