Is the World Savings Day or World Thrift Day still a big deal or was it ever a big deal around the world?
If there are also examples on what happens in various nations, like getting small presents/goodies (comic/toy/piggy bank) from the bank for depositing money was a big deal when I was a child in Germany during the 70’s/80’s.
From a U.S. perspective, I can state it’s not a thing, and hasn’t been one in my 50+ years of consciousnesses.
I’ve never heard of it in Canada.
Until very recently (I don’t know when they quit), Betty Crocker products in the USA still had coupons on the box tops, that were redeemable for silverware. That is the last product I remember that still gave away anything free with purchase.
In the 1950s in the USA, it was very common for packages to have included things “of value”, even it it was just collector/trading cards that could be scissored off the back of the box. Jams and condiments came in drinking glasses, with the caps just vacuum-pressed on, and many families had no other glasses in the house, except those containers repurposed. There were always some kinds of toys in boxes of breakfast cereals aimed at kids. Cracker Jacks don’t even have their famous Toy inside the box anymore, which was long virtually synonymous with the brand.
I do not understand why they don’t still do that. It would cost a cereal manufacturer nothing to print trading cards on the back of the box. One of the last things I remember was in the 1990s in Chile, Train chocolate bars had collectible cards inside the package with pictures of railway locomotives.
Printing little games and cut outs on cereal boxes is still being done - at least here - but no toy, unless there’s a promotion going on - but then you see a lot of boxes ripped open - guess this is why they are not common anymore.
The Barmbrack still contains a ring at Halloween.
The toys in cereal boxes etc seem to have been victims of health and safety legislation.
I too had never heard of “World Thrift Day”. Is it like the “World” Series? 
Nope, it’s a day where children go to the bank and deposit their savings and in return get an “encouraging to save” present from the bank.
Of cause you can deposit your money any other day as well, it’s sort of a special banking event.
Apparently Indiadoes it.
