Seconding the advice to just check local roasters.

If you’re looking for cheaper it’ll be challenging. Wegmans carries a couple whole bean decaf varieties (espresso and something medium roast). Trader Joe’s always seems to have whole bean French roast. And there’s some bulk ones on Amazon probably worth a shot - used to get SF Bay decaf there.

Probably good, not my thing since it requires filters. Very compact tho so yeah.

Espresso is hard to do at an office but a French press and hand grinder are very easy to keep in a drawer at your desk. And if you’re desperate you can use the drop brewer to get your hot water.
