SaGES is a 501(c)3 tax exempt organization, so donations to SaGES are tax deductible.
You can donate here.
You can also donate through amazon.com. Amazon will donate 0.5% of the purchase price of goods you buy from their website, if you start at smile.amazon.com.
When you first go to smile.amazon.com, you will be asked to nominate a charity to receive your donation. Type "Surveying and Geomatics Educators Society" into the box and click OK. On the next page, you will be asked to acknowledge that have to start shopping at smile.amazon.com to support SaGES. Check the box, click the "Start Shopping" button, and you are off to the website. If you are a Prime member, this will work as normal, as will the rest of the site.
