Sounds like we have a similar strategyYeah, the video could do without the special effects, but it's a good idea.
It's important to understand the supermarket's marketing strategy or business model, in order to gain maximum benefit from it. I only ever buy either products that I would buy anyway and which I know I'm going to use or need, or sometimes more expensive treats like salmon that would be too expensive for me to buy at their normal full price. Also I look at at the price per kilo to see whether it really is going to be a good deal or not... which the supermarket is obliged to show, but usually puts in really small miniscule writing, because they don't really want people to do this It's hardly a bargain to buy an item costing 10 euros at 30% reduction, when there is another similar item that only costs 6 euros, for example. I almost never buy brand names. These companies spend millions on their advertising campaigns, and that cost is inevitably passed to the consumer, they are always more expensive and not always better quality. The secret is to make logical decisions and not emotional ones - most people make emotional decisions, both companies and supermarkets are aware of this and exploit it to the full.
We're not big on branded products, but there are a few exceptions, mainly detergents and the like, our favourite coffees & teas and that's it I think.
We go to ASDA at the weekend but I pop in Tesco 1 or 2 nights a week after work to get fresh goods and I keep note of what things cost.
When you chuck in the odd trip to Aldi or a discount store we save an absolute fortune without going out of our way and not losing what we've saved in time and fuel.
