Harlow & Stitch review for Bundler ‑ Product Bundles App

Hi, I need to say that this bundler is GREAT but we ran into our first glitch yesterday.... We reduced our bundles from £29.99 to £24.99 and someone who had already had the bundle added to their cart at the original price managed to checkout for a total of £19.99! This is definitely not an error on our part as we have spoken with the customer and we cannot reproduce, so there must be an issue with the app. Please don't allow this to happen again otherwise we have to look elsewhere for an alternative.
