should have asked the LDS to match.If they could not they could probably done a dry suit speciality with the purchase of suit at no charge.I tried out a drysuit at a local LDS (not the one I frequent) in order to check sizing and bought it online. Saved me over $500. Is that really bad etiquette? It only took 10 minutes of their time.
I can see how it'd be bad if you tried it in their pool and maybe wasted an hour or so of their time. But still...
Maybe to relieve any guilt you may have on not purchasing at LDS where you wasted their time and used their facilities as a fitting room,used their expertise to get fitted properly,maybe even used their pool and gear, you should tell them what you did and offer to gift them some $ for their efforts.Just tried on the suit,give them $40. and bring a box of donuts and coffee.Tried on the suit and went into their pool bring the the same treats and $100. If the owner refuses the tip of cash give it to the salesman or staff member that assisted you..
Many here wonder why some LDS charge for their time fitting these "window" shoppers that get sized correctly and use their facilities and then purchase elsewhere. Gets to a point you can tell who is using you as a fitting room and who is serious about purchasing. If I think its someone window shopping I give the same level of assistance, but I try not to tell them what size items are.Maybe stores should remove size tags and code them in such a way that window shoppers cannot understand.
