The one I’m drinking right now is 6.76€ and the cheapest one is 1.28€.
First of all - what a price difference. Secondly, it’s actually not bad. It does have that faint “cheap coffee” taste, but after a few cups I barely notice it anymore.
The real question is: is the tradeoff worth it? Do I give up a few percent of enjoyment on every single cup just to save the equivalent of a month’s grocery bill yearly? I’m not in any dire financial spot - frugality is basically a hobby/lifestyle for me at this point - but it’s getting rarer and rarer to find ways to pocket savings of this level anymore.
Spend on what you value, not on what you can afford. Only you can decide what you value.
If you want to test, drink the cheaper coffee until you’ve decided you value the other enough to drink it.
So many folks try to reason this kind of decision out, when trying both options is easy enough.
