While toy hunting in Elizabeth, NJ, I visited a Dollar General store and came across a surprise: Authentics Alpha Series Shockwave! The Authentics debuted as a lower cost line of Transformers figures at stores such as Family Dollar, Dollar Generation and (on occasion) Walgreens. These figures use the "Evergreen" design of figures representing characters like Megatron and Optimus Prime without being tied to any specific continuity.
Check out my in package photos of Shockwave below. I do plan to review him at a future date. Shockwave was priced at $10 USD.
