Keep in mind hop presence fades. You may want to increase your hops to account for that.
I once entered a British barleywine into a comp and got dinged, "too hoppy for style". A year later it took second place in best of show judging.
Occasionally Amazon has a deal on bottles* and they qualify for free shipping if the total is over $35. Early this year I got three cases for around $18 each and they shipped free.

There is a hardware store closer that has some supplies, but when I checked them out they had hops and dry yeast out at room temperature making me less than impressed.
