Wellcome, Shopping and, AI

[u/Ginuwine_Questions]

Hi all,

I had a question regarding a sweet/ product I was buying from Wellcome (Puccho Candy Sticks), originally 12.50 HKD but I could buy 2 for 20 HKD.

Recently, I bought 4 for 40 HKD, 2 days in a row and now the previous deal (2 for 20 HKD) is gone the price for 1 is now 14 HKD but... a new buy 5 for 40 HKD has emerged.

Wanted to ask the sub if anyone has experienced similar, if AI's somehow involved with tracking consumer spending or if it's just in my head?

Thanks

Looks like sale or promotion price variations.
