Finally visited Amazon - 4 Star B&M store in Frisco last night, noticed that Amazon Echo Auto posted for $9.99. During the check out, this item rang up $4.99, which was a steal when compared to even $9.99. Even the sales associates at check out were surprised.
On top of it, they offered Alex Plugs for $4.99 in the store. Fellw SDers near Amazon 4 Star store should find this useful to pick up.
