We’ve been improving the speed of the local domains feature and have made great progress.
We’re happy to say that product grids with fewer than 10 products in them are now eligible, up from the previous 6 or fewer.
The free version has been updated with this speed-up.
It’s a shame that Zazzle don’t / won’t provide a way in their rss feed mechanism to resolve this. If they did, you’d be able to have local domains working on any size grid.
We’ve put in a request but their wheels turn ever-so slowly 😉
