Add plan 512 RAM for $2.5
I best for testing or small site
I strongly suggest against this, as this may create an influx of spammers and influence the service quality for others. The $5 Droplet is cheap enough for testing.
If somebody cannot afford $5 for server infrastructure, DO is not the service for them.

For testing, I don't see the need for this, as charges are hourly, and a $5/month VPS is already ridiculously cheap for testing purposes. For a small site, I can see how it could be desirable, considering the number of sites I host on a single $5/month VPS.

I know that Vultr hava this feat but here in Europe the 2.5 $ is always "Temporarily Sold Out". Sandbox environment are pretty nice. Wonder if its possible for DO to earn money on this.
