Thanks for using PriceCheck's search to find the best deals on laxatives, friend! Based on your mention of Movicol Powder, I'd recommend either the Movicol Sachets 8's for R100.95 or the Original Laxative Sachets 20 Pack for R169.99. Both offer great value and convenience as sachet packages of a trusted laxative brand. The 8-pack would be a more affordable option to try, while the 20-pack provides excellent value for longer-term use. I hope these results help you find fast, effective relief at a price that's kind to your wallet. Let me know if you need anything else - I'm always happy to help spare some discomfort. Have a smooth sailing day!
