Went into Sainsbury in Calcot today and found a stall handing out £1 off discount voucher for the Surf Small & Mighty 2x concentrated washing liquid. The voucher is specifically for Sainsbury store only.
Each bottle does 20 washes. With the £1 off voucher, I only paid £1.87 for each bottle. So that's 9.4p per wash!!!! cheaper than powder washes (probably not cheaper than those tesco value or sainsbury basic range).
The voucher didn't specify which fragrances is applicable but the photo shows carnival burst & tangerine and tempting nature & rain flower. The staff at the promotion stall says it should applied for all fragrances eitherway.
Oh and the voucher expires on the 27/3/09
