Fuel Price Week begin --/--

Feeling a bit shell shocked. A company i have not used for along time for my bulk fuel in the yard called today. 98.87 if i order 18k ltrs as normal the end of this week ■■?. My tank holds 30k ltrs so it will go in as got just over 8k in there at 4pm today. Do i gamble or say no hoping it will drop more ■■?
