Letraset has 6 single Promarkers for the price of 5, plus they are giving away a free Ultra-fine nib with each pen and free postage if you spend over £10. AND to sweeten the pot there is a further 20% off from now until Monday (8/29/11) with code LEAF2011. It cost me about $18 U.S.-that includes the S&H).
*sigh* I know my budget doesn't allow for art supplies this month, but some of my Promarkers are running out, and this deal can't be beat. More Ultra-fine Nibs, too! Poor budget. It's always getting stretched! I guess we'll be eating a lot more noodles this coming month!
