Just walked into a Shaver Shop on Boxing day and tried my luck for a Razorpit. It usually used to get some good engagement few years back most times when a deal was posted here. So, I have always wanted to try one. I was told the price is $4.95. I asked three times to make sure I did not mis-hear it. Although not as good as the best price of $1 in 2019 https://www.ozbargain.com.au/node/508788.
There are more items on sale. Please refer to the original deal https://www.ozbargain.com.au/node/822661. Thank you @Scrooge McDeal.
Just checked it is also available online, free to click and collect and $70 for free standard shipping. Although, it is too late for stocking fillers, a good price is a good price.

It claims to extend life of a razor by up to 60 times. I don't think that I have patience to track if I got 60 times or 59 times. The FAQs claim that it works on multiblade razors. I tried it yesterday, and seems to have worked for me.
Got one thanks, worth the gamble to see if it works.
