Yes, but only the two-handed clubs. And if you buy one of the +1 great clubs (it's one of the things that rotates through Dammon's inventory) the +1 carries through after casting shillelagh. So a 1d8 greatclub gives me 1d8+3 after casting shillelagh, and a 1d8+1 greatclub gives me 1d8+4. That's with 17 Wisdom.
But since it's a two-handed weapon, you can't use the flame blade along with it. And none of the vendors sell those. One of the masks in the Overgrown Tunnel - which you pass through to fight the Hag - is supposed to drop a regular one-handed club. The one-handed version is only a 1d4, but shillelagh is supposed to change any club to 1d8+wisdom. That coupled with a flame blade bonus action should do some nice damage. Or you could opt for a shield if you want to boost your armor rating.
I see no +1 version of the one-handed club, but there is supposed to be a Club of Hill Giant Strength in the Arcane Tower. It gives anyone wielding it 15 strength. Which is not a primary attribute for a druid, but could be nice to have. Especially if it means that at creation you can move some points out of strength to wisdom, or whatever other attribute you want to boost.
