American Eagle has scoop and v-neck tees, and their 'favorite boyfriend tanks' on clearance for $10. You will also save an additional 30% on clearance items (so now $7/each). They have an unadvertised sale where these items are Buy One Get One Half Off. Plus, use code 87279041 to save another 15%. Grand total of $8.93 for 2 tees or tanks, $4.47 each.
The 30% and 15% applies to all other clearance items as well (I'm not sure if there are any other unadvertised BOGO items). They had tons of clearance, and the tees and tanks available in every color and size when I looked through.
