BaByliss Curl Secret 2667U Hair Styler, with Auto Curl technology and featuring a ceramic chamber for smooth, shiny curls.
The product itself is £99. However, code 'TDX-PKJK' is worth £20 off a £100 shop from "qualifying electronics" and this qualifies.
You need to get the total over £100 for the voucher to work. Therefore you need to add something to bump it over the magic £100 mark.
The cheapest item I can find that you can add to take the total over £100 and qualify for the discount is the Tesco E122 Printer Ink Cartridge which costs £1.43
£99+£1.43 (filler product) makes £100.43, take off the £20 and you're left with £80.43 to pay.
(Of course you could spend a few pounds more and pick a filler item you actually WANT - the above is just the cheapest combination that looks like it will work)
Free next day click and collect.
NOTE: this item is in Clubcard Boost so you can pay for it using Clubcard vouchers at twice their face value.
