I just got mine from there yesterday
This range is currently £1.33 each in Waitrose (until 7 Aug) https://www.waitrose.com/ecom/shop/offers/14743914
How can I make calls on this?
You can buy the Lavender '1 pack' for £1.33 without any qualifying order. Or 3 for £3.99 with a purchase of £20 or more. Hmmm. Also, if you're really, really, sadly, pathetically desperate to save money, but still require some soap for the bathroom sink, you can save £0.17 and buy used a used 'pack of 1' Lavender for £1.16. Yes, you read that right. You can buy used soap, not making that up. Check a look.
Soap is, by it's nature, antibacterial. This new nonsense "antibacterial" label is unnecessary and confusing for laypeople. Edit: Suppose I should include a link: https://www.fda.gov/ForConsumers/ConsumerUpdates/ucm378393.htm
