but don't you need to buy their strut/shocks???
No. You don't have to buy
their shocks/struts.
They lend out the spring compressors,
brake tools, exhaust tools, etc., etc.,
for free.
Just as clbanman says, you only need
a credit card or refundable deposit and
some i.d.
At my local Can. Tire they have a list of
all the tools they lend out (with pictures)
at the service counter.
