75% off Magnetstreet Invites- worth it??

I designed a sample invite set on magnetstreet.com and saw they are running a 75% off sale until April 14th! My wedding isn’t until October, so we don’t have our wedding list complete, but I know the number we’d order.
Does anyone have opinions on 1) ordering invites from here, the quality, etc? 2) whether a 75% off sale comes along very often? 3) whether you think it would be fine to order invites this early and just say “see our wedding website for details on accommodations” (because we haven’t decided if we’ll need to reserve hotels yet). It feels early to order invites but also a great deal for invites (plus details cards and envelopes!)
