STANDARD, PRIMARY, DM AND VARIANT COVERS
Standard and Primary covers are widely available through general retailers. They often have higher print runs and can be cheaper, especially during sales.
In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.
The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
