Day 5 $184.99, $62.50, $50.00, $129.99, $129.00
Day 6 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00
Day 7 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00, $900.00
Day 8 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00, $900.00, $7.25
Day 9 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00, $900.00, $7.25, $699.34
Day 10 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00, $900.00, $7.25, $699.34, $476.67
Day 11 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00, $900.00, $7.25, $699.34, $476.67, $220.69
Day 12 $184.99, $62.50, $50.00, $129.99, $129.00, $27.00, $900.00, $7.25, $699.34, $476.67, $220.69, $219.16
