This page contains all the currently existing ways to support Math ∩ Programming, and as people suggest new ways (for e.g., lack of cooperation by PayPal or shipping concerns with Spreadshirt). I also want to be as transparent as possible as to where your money goes in terms of merchant fees for the transactions.
If you want to read my shameless request for support, see this blog post.
Here are all the ways you can support this blog, in increasing order of difficulty.
Whitelist your ad blocking software for this domain. As of April 2013, this blog serves ads which fund this blog (as opposed to WordPress, which has been serving ads on my blog since it started anyway). The ads pay per page load, not per click, so simply whitelisting this domain in your adblock software while you read will implicitly generate a small amount of revenue. I have no idea if actually watching an ad results in extra funding.
Share. Sharing my blog in your social network will lead to higher traffic, and this will indirectly lead to funding for this blog in a variety of ways.
Donate directly via PayPal. 2.9% + 0.30 USD of each transaction goes to PayPal.
Buy merchandise via Spreadshirt. My commission varies around 5.00 USD per item (depending on what I list as the price of the item), and the rest of the price of an item goes to Spreadshirt for their service in creating and shipping the physical item.
If you have a different preferred way of transferring currency that isn’t mentioned here, please leave a comment and I’ll do my best to accomodate.
Thanks so much for your readership. It honestly keeps this blog going strong, and regardless of your choice to support or not to support, I appreciate every reader who stumbles across this humble blog and enjoys it.
