It is necessary to raise the net of small sites with woo-commerce and there are two solutions: do WP multisite or make a single domain to put plug-in that will make a lot of small shops type shop.ru/store/xxx, shop.ru/store/yyy and mod_rewrite make it into xxx.shop.ru, yyy.shop.ru
In the first case, the right to be given away somewhere at the level of WP, in the latter case where the rights will be distributed at the level of plug-in that keeps stores.
Who thinks what option is best?
