136 Huggies Crawler nappies + 480 Huggies wipes for $59 at Babies R Us (Wednesday)
As nappies generally tend to be very popular during these types of sales, I saw that they're going to be selling a 136 mega pack of Huggies Crawler Nappies (6 to 11kgs) for $39 when you spend $20 or more. The same 136 pack of Huggies was going for $49.50 at LetsBeClean.com, $54.89 at GoToddler.com.au and $57.95 at The Nappy Shop Australia.
To qualify for the $20 spend, you could buy a two pack of Huggies unscented or scented refill wipes (2 x 240 wipes) on special at this exact price. The average market price on these looks to be around $14.99 per pack elsewhere although I did find manage to find them slightly cheaper at Chemistwarehouse.com.au for $12.99 per pack.
By purchasing the Huggies Crawler nappies with the 2 pack of wet wipes you'll end up paying $59 in total. But even if I take the cheapest prices from other retailers on each of these items, you're still making a saving of $16.48 ($75.48 - $59) or 22%.
Plenty more items to choose from in their sales catalogue, so if anyone manages to find something which can be price matched and beaten by 10% elsewhere - please comment below!
