Your total is $8.96 including delivery for 3 pairs due to pricing error.
Bras N Things running a 3 for 2 knickers sale.
White 'Smooth Comfort V-String' knickers are also on sale for $6 (normally priced at $16.99)
If you add 3 pairs, it subtracts $16.99 from your total.
Ends up being $8.96 as they also have a $7.95 flat free shipping cost - but it ends up being cheaper with this factored in anyway
Note: it only works for quantities of 3, if you add 6 pairs instead the pricing error is gone. So recommend buying in quantities of 3 for best value.
Not sure when this will be corrected.
