Real Canadian Superstore prices for my hummus since this started:

Swapping from Peru-made lemon juice for my hummus to malt vinegar - cost down from $2.79 to $1.50
No Name Chickpeas to Unico equivalent - $1.50 to $2
Using canola oil and not olive oil as suggested by nearly every recipe - no name olive oil costs $12 for 750 mL whereas canola oil costs $8.29 for 3 L getting you more for less with hardly a change in the recipe
Tahini - found a good recipe from Diabetes Canada that completely removes this ingredient, saving me a solid $10 for a jar
To finish things off, while both Canadian, swapping from sandwich bread to sliced French bread for dipping - $1.97 to $1.25

Cost of hummus ingredients goes from $28.26 to $13.04 with the added bonus that one of those ingredients lasts three times as long.

People need to learn substitutions in their recipes, that alone saved a tonne. I pay more for Canola oil personally cause I get Canola Harvest and not the no name brand since they're unionized, but even with that in mind you're paying less than olive oil for like, double the amount.
