I paid a high of 1.139 last year and that was outrageous!
This year I "pre-bought" 1000 gallons at 1.499 with a down price protection plan. I will not pay more than 1.499, but if prices drop I will be charged the lower price. My pre-buy at that price was pretty good considering the best 'off the shelf' price I have seen locally is 1.899 and many companies are charging more than 2.00 a gallon for people who are not 'preferred' (do not have their furnaces cleaned & serviced by the oil company, do not buy Propane or gas as well as oil, etc) customers.
If you were not paying attention and didn't or couldn't budget for it, the HHO prices can be a real bank buster if they don't drop before winter sets in.

You can do your own "prebuy" by using mini oil options.
