I just started testing IVM 4.02, and will need the Enterprise version for all the OGMs I need to write. NCH is having a June "sale" where the price is $179.40. Is this the always on sale price or will it probably go up in July? I'm still in the testing phase until the first week in July, but don't want to end up paying more. Is the sale because a new version is on the horizon with an upgrade cost? Thanks.
