Lowe's: Knock Out Roses 75%-90% Off

Last week at Lowe's I noticed a sign that said 75% off roses.  I went and looked and saw they were priced $7.25 regularly $28.98 so I snatched one up and brought it home.  My mom then came over and saw mine and wanted some too.  She bought six and paid $3.62/each. 

These are beautiful roses and I have a brown thumb and thought if I kill it I will only be out $7.25.  Wait only $3.62 because they gave me a price adjustment.  Thanks Lowe's.
