The 50% sale doesn’t apply to the Crazy Domain Insane plan (L1), with or without a promo code.
The Code Monster (L3) is the one on sale at Sweet Dreams (L2) pricing–which is still more than L1, if that’s all you need.
If you sign up for L3/Code Monster, you get to keep the 50% pricing when you renew.
If you’re asking if you can do L1 for the first year with a promo code, which is barely over $20 for the year… then sign up for L3 at 50% off, then that would depend on whether they’re still running the sale.
It seems like the sale has been going on forever, but if you’re set on having L3 @ L2 pricing, I probably wouldn’t wait a year.
I’d guess (but don’t bank on my guess!) that the price is there to stay, but it probably gets more sales when you leave it as half-off, rather than just setting the price and dropping the L2 plan.
Save up to $96 at Dreamhost with ALMOST97 promo code (I get $1).
Or save $97 with THEFULL97.
