My mother in law purchased a gift certificate for me for 5 underarm treatments. At the time, I was breastfeeding and they do not do any treatments on breastfeeding/pregnant mothers, which I understood. However, they told me the certificate does not expire and can come back any time. By the time I was done breastfeeding/having babies, they refused to let me use the certificate stating it's only good for 2 years. The certificate does not have an expiration date on it and they were very rude to me for inquiring about it.
