You can buy already milled strips. However, I find that only works best for the wealthier than I. I have milled miles of my own strips at fraction of the cost of store bought strips.
Here's an example: One supplier charges $.60 ft. for Western Red Cedar strips, a common boat building wood. The average strip built kayak uses about 1300' of strips. At $.60 per foot, that's $780. Add Truck shipping say $100= $880.
You say you don't have the tools to make your own.... How much does a really good table saw cost, $500? $880 less $500=$380. Cove and bead router bits: $40. $380 less $40=$340. Don't have a router? $150 gets you a good one. $340 less $150= $190. Don't have a router table? I made mine with cheap MDF for less than $10. $190 less $10= $180. $180 should buy all the lumber needed to make all your strips.
Last weekend I milled one 1X6 (7/8" X 5-1/2") Basswood board into 1/8" strips to use in my Tear. I wasn't concerned with getting the most strips from the board, so I ripped the strips at 3/16" or bit less. I ran them all through my thickness planer (not necessary for boat strips) to 1/8" nice smooth very bendy strips

Even with all the unnecessary waste, I ended up with 180' of strips from one 10' board. The board cost me $21.
If you have the $ resources, and want to save a little time, by all means buy your strips. They are not overpriced, a lot of work goes into them. I am suggesting you can make your own for less if your poor like me
