I have already discussed this question for a long time on the channel, but judging by the fact that recently you have started asking me more and more often, it is worth touching on this topic again!
In fact, everything is simple ...
I recommend not writing prices in publications if you / your manager knows how to sell really cool in correspondence. Because when there are no prices, you get a lot more questions in Direct / comments from subscribers / potential customers and you can better reveal all the values of your product to the client, thereby generating 20-30% more sales
Otherwise, it doesn't matter if you have a written price or not, because sales will come out + - the same! (Only here in the option without prices, you will spend much more time "raking direct")
This advice applies to almost all Instagram accounts with an average check for products of up to $ 100 (If your product is more expensive, it is better not to write the price at all and tighten the level of your sales)
