How soon can I crush my grain before brewing

I currently get my grain crushed at my brew store 20 minutes away. I am going to have my grain crushed on Thursday when I pick it up but I will not be brewing until this Sunday. Is crushing your grain 3 days before a brew detrimental to the quality. I know it is not ideal and I am planning on buying a grain mill in a few months. Just wanted to know if anyone can tell the difference when they crush their grain this early.

Thanks for the help!

It will be fine. Crushed grain can last for up to 3 months if well kept.

Agree. I've crushed 4 batches of grain at the brew store before, brewing those batches within a few months of crushing. My brew store is too far away to drive for one batch. I keep it in a cold sealed tupperware container. It isn't ideal, but the beers turn out fine.

I'll pony up for a mill someday soon as I would like the freshest possible beer I can make. After all, i'm a stickler for fresh ground coffee, why not fresh ground grist?
