The issue is also offered in several variant cover editions, including a 1-for-15 Stefano Caselli Variant (SEP100571, $3.99), 1-for-25 Marcos Martin Wraparound Variant (SEP100573, $3.99), 1-for-100 J. Scott Campbell Spider-Girl Variant (SEP100572, $3.99), and a Blank Cover Variant (SEP100570, $3.99), of which you may order as many copies as desired.
The Campbell Sketch variant has been declared as both a 1:100 variant and an MRCC variant by different sources, it also seems to sell for a lot less than the color variant.
