GST Rollback (of a whole whopping 1%...)

Since July 1st the only impact I have personally experienced from the rollback of the GST is that now my Tims coffee costs $1.24. Which means the cashiers are always out of pennies or my pockets are always full of pennies - though every 4th coffee I have enough pennies to pay the 4 cents directly. Honestly, I don't need a penny taken off the cost of my morning coffee. I know that there are lots of people out there that will really benefit from this tax reduction, but the real savings will come to people making large purchases, not to the people who have trouble buying their groceries. Rather than give 1% back to the population, why not divert it to charity - which will likely have a larger impact on helping the people that need it most...?
I am not a fan of the United Way, personally. As a charity it is great and I support the idea wholeheartedly, but as an individual I feel that I can have a larger impact on the things that matter most to me by funneling my money to the specific charities that I want to support. I try to take the "think globally, act locally" frame of mind when donating, and also try to help people as well as the planet. So I have actually come up with a matrix of charities to which I contribute.
But back to the GST rollback, the United Way is a great charity for corporations and government since it eliminates allegations of favouritism or discrimination from those donations - in effect not offending anyone in particular, or offending everyone by about the same amount. Anyway, funneling 1% of purchase costs into some form of charity could make a significant difference to those who need it most - for a while anyway. Eventually there would be corruption and misappropriation of funds - there always is when large dollars are involved, but by then some people will have received some help and there will likely be some other crisis that will need extra funding (like alternative energy options...?).
Well, that's my 2 cents anyway - or in this case, 1 cent...
