Hey knotties! Hope all of you enjoyed Superbowl Sunday.

So the question is, how many registries should we have? So far we've registered at Bed, Bath and Beyond. We loved a lot of stuff there but some of it was expensive, so we're considering also getting a registry at a big box store so our guests have cheaper options. Thoughts?
Re: How many and which types?
We have Macy*s, BB&B, Target, and REI.
Only the first three are linked on the wedding website, and REI has just a few items on it. FI is a huge gym rat and we go out paddle boarding/kayaking with some of his buddies from our gym; they're the only ones who have asked him about it.
I only did our Target registry because it's such a popular place to shop among my friends, and my BM suggested doing one there before the shower.
