Two sets of the generic set of boules ordered from the Petanque America online store. Comes with two jacks.
Cost = $50 + shipping = $63
There has been a slight price increase since this post was first published in July 2012.
I found a very nice metric tape measure for around $10. Read buying a tape measure.
I made a usable throwing circle for $3.00, using plastic tubing that I bought at my local hardware store. Read about how to make an inexpensive throwing circle.
A boule towel
For toweling off the dusty boules after the end of rounds, I cut the leg off of an old pair of jeans in my rag bin. Cost = free.
$63 (boules) + $10 (tape measure) + $3 (tubing rond) = about $76.
