If I believe a service is overcharging me for a transaction fee, I use another service.
If, however, a service offers LN payment, I prefer that service over anything else
Nominally OT here but coinpayments.net can at times have really crappy conversion rates.
I too use LN whenever possible. Do a lot of GC purchases at bitrefill.com and fold for stuff I need in the real world.
Have some channels pending open at the moment I just opened them with a low fee figuring they will open in the next few hours or overnight.
Then I can spend the next few weeks, or months if I keep the 'add to shopping cart' to a minimum.
The problem still is getting people to use it.
I even setup my own BTCPay server to take payments ( https://paydave.lightning.ninja/ ) and almost nobody used it so I stopped posting it when selling stuff here.
I thought that when I was doing some $1 raffles people would hop in and buy a ticket or two for a buck with lightning with the low fees but nope.
