I wouldn't take it that way personally. It's definitely a cash grab but I don't think that the eight billionth variant of any of these is going to hold huge collector's value and I don't think (or hope?) that no one is scooping these up with an appreciation expectation. Walmart and Target's strategies also seem to differ for me. Target aims for high-popularity pop releases as well as albums that were never printed/went out of print from classic/legendary artists (as well as high end GH represses like Wally World). Walmart is willing to go more for older GH re-releases. Both of these make sense based on their expected markets to me. I think if anything it's a really good sign for the industry that huge retailers are willing to dedicate shelf and warehouse space to a larger, more finicky, premium priced physical medium when their whole business model is to not do that. It makes a lot more sense for a Walmart, Target, etc. to take on "exclusivity" of basic pressings of high popularity artists that one of the vinyl curation clubs doesn't have much interest in. The consumers is possibly buying as a gift or, if for themselves, will prioritize different things than the audiophiles that traditionally inhabit this space.
Like...the AT-120 is the highest end turntable in Amazon's listing with a TON of Victrola/Crosley knock off/All-in-ones, there's a big market for people trying to get in cheaply and listen to the things Walmart/Target are exclusively pressing here.
If anything, it feels a lot more like sports cards to me where the "retail" market and "hobby" market are two very different beasts with re-seller overlap.
(Edit: Now is it a bubble? Quite possibly. I know a lot of money I'd normally spend on live shows or, in prior years, digital ownership has been consolidated into Spotify and left me a good amount of free money to go towards physical ownership of vinyl. It's really possible that in 2022, if live shows are back, it reverses where the commemoration of music is standing in a crowd as opposed to owning the vinyl...we'll see.
