When Lois and Reese are seen in the store, Lois gives Reese a pile of clothes to try on. Reese complains that she gave him a pink shirt and he does not wear pink. The shirt disappears and reappears in the pile between shots. Then, when she says she will get him a different one, she takes a red shirt off the pile, and Reese is still seen holding the pink one.
At the 80% off sale Renee says that a $200 dress has been marked down to $30. However, 80% off $200 is $40 not $30.
