Need some suggestions

Im running meta ads for a fmcg brand which sell A2 ghee and cold pressed oil and price is on a higher side. I’ve tried multiple ad angles, multiple offers also tried targeting different segments example parents with small kids, pregnant women, health conscious etc but still cost per perchase is very high ROAS 1 or sometimes goes 0.5 also, website is also well built with all modern functionality with easy checkouts practices.

Need some inputs here thanks in advance
