"Yankee candles £3 at Tesco (had loads!)" she wrote alongside the picture.
And other shoppers quickly took to the comments section to weigh in, with many admitting they were already planning a trip to their local supermarket on the hunt for the bargain buys.
"Which Tesco?" one person asked.
To which Melanie replied: "Eastbourne, but I presume it's all stores that sell them."
"Let’s go tomorrow lol," another added, tagging a friend.
"Keep a lookout for the coconut one," a third instructed a pal.
"Love a Yankee me....not that I've got loads or out," someone else said.

"Like me after Christmas - I went mad looking and getting more," another admitted.
"I have the Coconut one, smells good!" someone else wrote.
However, another pointed out that there's a reason the candles Melanie found were so cheap.
And that's because they're actually from Yankee's Home Inspiration range, and retail at full price for around £6.
"Not the original Yankee candles," they wrote.
"They're Home Inspiration - good bargain though!"

One such dupe is the Sweet Blossom candle in Aldi, which is the store's version of Yankee's much-loved Sugared Blossom scent.
Posting a picture of the dupe she'd managed to buy in the store on the bargain hunter Facebook page, Chloe wrote alongside it: "£3 in Aldi and smells exactly the same as the Yankee sugared blossom!"
"Definitely saving a few ££," she added.
"Burning it now and can smell it all over the house," one person wrote in the comments.
"Bought some of these for Xmas and they are exactly like Yankee, will defo be getting these in future," another vowed.
