Newbie here. I bought some Rite Aid blades for like $8 for a 15 pack. I'm happy with them and some speculation is that they are personna blades. Is it correct? Is there a source for this blade cheap? It seems Rite Aid prices are way too much.
The blades are likely either Personnas or Dorcos. I just bought 100 Personna blades for $13 shipped within the US off of eBay in a BIN transaction (no carrier, just a cheap thin cardboard box containing the blades). $8 for 15 blades is ridiculous (they are less than $2 per ten on Walmart.com), even Feather blades (the best blades available but at $30 per hundred minimum) are cheaper than that! If I could see the carrier the blades came in (that white thing that you slide blades out of one by one) I could tell you if they are Personna or Dorco. Personna carriers have more of a curve at the longer sides of the carrier than Dorco does. I would rather use a Personna over a Dorco but in a pinch either will do the job.
BTW I like Astras as well, I have 200 of them in my medicine cabinet as I type.
