Do we like line shopping?

So, we all line shop, right? I saw DraftKings had a -3.5 line on the Bills, but FanDuel was giving -2.5 – that’s a big difference if you’re betting close games! Line shopping can save ya cash and lower risk, but I’m wondering how many of you really do it consistently? Like, is it worth jumping between apps for every single bet, or do ya stick to one place?
Is cool to think of it like “best bonuses” but sometimes I feel them as a hook, you take the bonus but the line are not so convenient…
