EReplacement thumbs up, Snapper thumbs down
Great service, parts arrived on time, just as described, thanks. However: Prices on Snapper parts have gone thru the roof. OUTRAGEOUS! Prices have gone up 2, 3, 4 times from what they were just couple years ago. Example.....grass catcher bag.....have been around $35 to $40, for the past few years.....now $85. I learned Briggs & Stratton, owner of Snapper has filed for bankruptcy. I’m not surprised. Have owned Snappers for 38 years...will be looking elsewhere from now on.
